This error comes when you try to upload media file such as image, video by Wordpress browser uploader or flash uploader. Wordpress shows this error when temporary upload folder not configured in php.ini file. It is possible upload temp folder is configured but path entered does not exist in the file system. To fix the issue you just need to check and correct temporary path in php.ini file. If path is in-correct you need to correct folder path or if no folder path given then you need to set temporary path.

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/

I recently encounter this issue on my client wordpress mu blog.  When i open main blog page after installation an infinite loop occur and stop at dead end in Firefox. I searched a lot about this on wordpress forum. Surprising, issue is stated everywhere in the forums and blog but no solution was suggested.

Why Redirect Loop?

The issue arise because database was not created during wordpress installation but word press config file was written. WordPress uses wp-config.php file to store database configuration.  If WordPress find this file in the  installation directory then no further installation procedure begin. WordPress now look at DB to load default blog but there is no table in the database. Again, control goes to install procedure but WordPress understand blog already installed because WordPress config file is present in root folder. Once again WordPress try to load blog from database and redirect loop occur.  I hope WordPress guys will fix this in future releases.

The Fix

The fix is very simple. Simply, rename or delete WordPress config file and re-install wordpress mu.  Make sure database user you are using during installation have sufficient permission to create and manipulate database tables.

Today, i  discovered that my blog feed was showing error in Firefox and other browsers.  This error comes if white space of empty line at the start of xml feed content. Your xml feed content should start with xml declaration without white space or empty line. Blank lines or white space can be introduced by theme code, plugins, wordpress code or wordpress configuration file. A quick fix is check files you have recently edited.

How to Fix

• Deactivate all plug-ins loaded and activate plug-in one by one to catch exact plug-in creating problem.
• Try disabling wordpress cache plug-ins. Wordpress cache plugin don’t work well with some hosting.
• Check your theme files, wp-config.php file for blank lines. It is hard and time consuming to check all wordpress core files. Thanks yo fiyaga for usefull wordpress plugin “Fix RSS Feed” that automatically detect blank or white space in the wordpress core files.
• Make sure to ping your feed in feedburner or similar service you are using.

If you are facing this error and could not find a solution then you are at right place. I hope what i am sharing here could solve your issue.

This error comes most likely due to corrupted installation media so to work correctly you just need to make sure installation media you are using is fine.  So do the following to make sure your installation media is error free:

1. Make sure ISO image you have downloaded is not corrupted in transfer.
2. Make sure ISO image is not corrupted during transfer from one PC to another PC. (I am specially mentioning here because this was my case. I have downloaded ISO image on one machine but intended installation machine was different. so the transfer media such as USB hard disk or Pan Drive was used.)
3. Make sure your ISO image burned without error on DVD.

Now, next question is how you can verify downloaded ISO file.  There are several way to do verify ISO file accuracy.

1. Try to extract iso file content in a folder.  ISO files should be extracted without error. You can use WinRAR or  Magic ISO to extract ISO image file content.
2. There is a chance to extract ISO file without error even if few files inside ISO are corrupted so you need to double verify image file. Follow next step for additional verification.
3. Download MagicDisk (Free Utility) and install in your system. MagicDisk is free virtual disk program that can mount any iso or nrg(nero image) to a Virtual CD. Try mounting downloaded image file from this utility.  If image file loaded correctly in a newly created Virtual CD disk then your installation media is fine and you can burn ISO file into DVD media.
4. Make sure to check data validation after DVD burning so you can make sure DVD burned is error free.

Vendor() function basically used to load third party library in CakePHP. This function have been deprecated in the recent CakePHP releases.  The vendor function in earlier CakePHP releases has been replace with new App::import method that is more user friendly and allow you to include third party library in several ways.

To fix the issue simply replace vendor function with new method.  New import method return boolean true or false depend on the library loaded or not.  This is useful in some context.  With new import method you have option to verify third party library loading and act accordingly so your application never fail.

Old Method

vendor('facebook/facebook');

New Method

App::import('Vendor', 'facebook/facebook');

Cryptography is the process of transforming digital information into an unintelligible form so that it can be sent over unsafe channel of communication.  The transformed data called cipher text that is in the form that nobody can understand.  The transformation process handled by a data key.  This key required to transform cipher text into original state. The stage of conversion of the digital data into unintelligible form is called Encrypting or Encoding.  Reconverting the encoded data back into the original form by the authorized person using the appropriate key is called decrypting or decoding. Below is basic diagram explaining encryption and decryption process.

ENCRYPTION:

Ascii Text Or Data –> Algorithm –> Secret Key –> Cipher Text

DECRYPTION:

Cipher Text  –> Algorithm –> Secret Key –> Original Data

Encryption Algorithm

• Transposition Cipher
• Code System
• Data Encryption Standard (DES)
• RSA Approach
