Here are some reason that prevent Word Press to run wp-cron correctly.

• Server doesn’t have DNS, and so it can’t figure out who “example.com” is, even though it is *itself*.
• Server administrators, in a misguided attempt at security, have blocked “loopback” requests, so it can’t actually make a call back to itself.
• Server is running something called “mod_security” or similar, which actively blocks the call due to brain-dead configuration.

There is simple to complex workaround to solve this issue. This problem automatically fix when your server is configured to run wp-cron properly but it require server root access and extensive server administration knowledge. So server configuration method is simply not for everyone to use. There is simple workaround to fix this issue that force wordpress to run wp-cron using alternative method that does not rely on web server configuration. To fix the issue add below line in the wp-config.php file. This line can be add anywhere in the wp-config.php file.

define(‘ALTERNATE_WP_CRON’, true);

This should restore wordpress schedule functionality.

You can easily fix this by editing php.ini file. Most of the shared hosting provider now support custom php.ini per account. It means you can have you own php.ini and optimize php setting according to your need.

Apply following steps to complete this task.

1) Find out exact physical path of your account public_html folder. Create a text file and name it phpinfo.php. Add below lines in the file. Save file then upload file in the public_html folder of your server.

<?php phpinfo(); ?>

2) Run phpinfo.php file by pointing your browser to the file. http://www.yourdomain.com/phpinfo.php. Replace yourdomain.com with your actual domain  name.

3) Search for two entries _SERVER["SCRIPT_FILENAME"] and Loaded Configuration File. Note down value against these entries.

In my case value for above entries are

_SERVER["SCRIPT_FILENAME"]  -> /home/homefolder/public_html/phpinfo.php

Loaded Configuration File -> /etc/php/php.ini

4) If your hosting account support custom php.ini or you have server access then you can complete following steps otherwise you need to ask your hosting company to complete this for you.

If you have server command line access.

1. Create a temporary folder called “tmp” within your public_html folder from FTP. Now temporary folder path is /home/homefolder/public_html/tmp/
   
2. Login into the command prompt as server administrator.
3. Type below command and hit enter
4. $ sudo nano /etc/php/php.ini
5. It will open php.ini file in nano visual editor with root privileges. Enter root password if asked.
6. Find upload_tmp_dir and un-comment it if commented. “;” used for commenting purpose in php.ini. Simply remove this special character to un-comment line.
7. Change upload_tmp_dir value to /home/homefolder/public_html/tmp/. You line should appear similar to next line (8).
8. upload_tmp_dir = /home/homefolder/public_html/tmp/
9. Save php.ini file and restart apache.
10. Now again run phpinfo.php file in your browser. New value should appear in your php info setting.

If your host support custom php.ini

1. Create a temporary folder called “tmp” within your public_html folder from FTP. Now temporary folder path is /home/homefolder/public_html/tmp/
2. Create a text file called php.ini in your system and paste content in step (8) specified above.
3. Save file and upload to your public_html folder in your FTP.
4. Run phpinfo.php file in your browser. New value should appear in your php info setting.

Error should disappear now. However, in some cases you may still get same error. For those cases try removing trailing slash at the end of path. After the change path would be  /home/homefolder/public_html/tmp instead of /home/homefolder/public_html/tmp/

Good Luck

Use below mentioned command to format USB pen drive.

Make sure USB pen is not mounted.

If mounted Click on Places > Computer > Select USB pen > Right click > Select Unmount Volume to unmount volume USB volume.

Check partition label using fdisk command or gnome graphical partition editor.

mkfs command

In my case USB partition label is /dev/sda1. Please check at your end using above method. Be careful using while using partition label, Wrong partition label can wipe out your entire hard disk or specific partition volume.

To format open terminal window and type the command

$ sudo mkfs.vfat /dev/sda1

For LINUX/EXT3 file system use below mentioned command

$ sudo mkfs.ext3 /dev/sda1

Follow these steps to install Rar Support in your Ubuntu Linux Distribution.

Open Terminal Window and Run the below command. You may ask to enter admin password if you are not login as root.

sudo apt-get install rar unrar

The above command will install rar/unrar capability in your ubuntu linux box. You should now able to UnRar archives using Archive Manager.

cd : Change directory
Examples:
cd ~ : Change your directory to your home directory.
cd – : Change to the last directory you were in.

tail : Reads and display the end of the file
Examples:
tail /var/www/me.txt : Display last 20 lines (by default) lines of the given file.
tail -f /var/www/me.txt : Watch the file continuously, while it’s being updated.
tail -400 /var/www/me.txt : Print last 400 lines of the file to the screen.

more : Open file one screen at a time.
Examples:
more /etc/log.txt : Opens the file one screen at a time rather than all at once. Press Space to go to next page.

pico : easy to use file editor
Examples:
pico /home/mysite/public_html/you.html : edit the you.html file from the public_html directory.

vi : popular editor in linux, have lots of features but harder to use
Examples:
vi /home/mysite/public_html/you.html : edit the you.html from the public_html directory.

grep : looks for certain patterns in files
Examples:
grep root /etc/passwd : shows all matches of root in /etc/passwd
grep -v root /etc/passwd : shows all lines that do not match root

touch : create an empty file
Examples:
touch /home/mysite//public_html/new.html : create an empty file called new.html in the directory /home/mysite//public_html/

ln : create’s “links” between files and directories
Examples:
ln -s /usr/local/apache/conf/httpd.conf /etc/httpd.conf : Now you can edit /etc/httpd.conf rather than the original. changes will affect the orginal, however you can delete the link and it will not delete the original.

rm : delete a file
Examples:
rm filename.txt : Deletes filename.txt, It will confirm you before deleting file.
rm -f filename.txt : Deletes filename.txt without confirmation.
rm -rf tmp/ : Recursively deletes the directory tmp, and all files in it, including subdirectories.

last : shows who logged in with the time
Examples:
last -20 : shows only the last 20 logins
last -20 -a : shows last 20 logins, with the hostname in the last field

netstat : shows all current network connections.
netstat -an : shows all connections to the server, the source and destination ips and ports.
netstat -rn : shows routing table for all ips bound to the server.

top : shows useful live system info
processes in a table format, memory information, uptime and other useful info. This is excellent for managing your system processes, resources and ensure everything is working fine and your server isn’t bogged down. top then type Shift + M to sort by memory usage or Shift + P to sort by CPU usage

ps: ps is short form of process status, equivalent to the top command. It’s used to show currently running processes with their PID.

A process ID is a unique number that identifies a process, with that you can kill or terminate a running program on your server (see kill command).
Examples:
ps U username : shows processes for a certain user
ps aux : shows all system processes
ps aux –forest : shows all system processes like the above but organizes in a hierarchy that’s very useful!

file : attempts to guess what type of file a file is by looking at it’s content.
Examples:
file * : prints out a list of all files/directories in a directory

du : shows disk usage.
Examples:
du -sh : shows a summary of total disk space used in the current directory, including subdirectories.
du -sh * : same as above, but for each file and directory. helpful when finding large files taking up space.

wc : word count
Examples:
wc -l filename.txt : tells how many lines are in filename.txt

cp : copy a file
Examples:
cp filename filename.backup : copies filename to filename.backup
cp -a /home/mysite/old/* /home/mysite/new/ : copies all files, retaining permissions form one directory to another.

kill: terminate a system process
Examples:
Syntax: kill -9 PID Examples: kill -9 431
Syntax: kill PID Examples: kill 10550

# to stop php startup errors
php_flag display_startup_errors off
# to stop all php errors and warning
php_flag display_errors off

You can also control level of error reporting. Here is the .htaccess syntax:

# php directive for setting error level
php_value error_reporting integer

Example:

# report everything except run-time notices.
php_value error_reporting 8191
# report both fatal and non-fatal compile-time warnings by the Zend Engine
php_value error_reporting 128
# report run-time notices, compile-time parse errors, run-time errors and warnings
php_value error_reporting 8
# report fatal run-time errors and unrecoverable errors
php_value error_reporting 1

And, A Record simply creates an association between a domain/sub-domain name and an IP Address.

Example CNAME
gallery.bala-krishna.com -> gallery.another-domain.com -> 64.1.236.65

you can see above CNAME require two DNS lookup to translate domain/subdomain to an IP Address. If client request for gallery.bala-krishna.com then DNS record will return gallery.another-domain.com then gallery.another-domain.com has to query DNS to translate gallery.another-domain.com into IP Address.

CNAME Record Syntax:
www? ? 14400? ? IN? ? CNAME? ? bala-krishna.com

Example A Record

gallery.another-domain.com -> 64.1.236.65

In case of gallery.another-domain.com, A record directly point to an IP Address so the DNS lookup directly returns IP Address to the client rather then domain/subdomain. hence only one DNS lookup required.

A Record Syntex:
ftp? ? ? ? 14400? ? IN? ? ? A? ? ? 67.159.45.3
