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/

Create .htaccess file or use existing .htaccess file in your hosting site. Add below line at the top of file content.

# 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

CNAME stands for Canonical Name for a domain. CNAME is an alias records that create association between a sub-domain and antother domain or subdomain.

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

PHP compiler generate fatal error if you use function return value in read/write context. Although this is not applicable for all PHP supported function but PHP function like empty does not support use of the function in this way. In other words, php empty function cannot check the return value of a function or method. It can only check variables so use only variable inside empty function. Any other function or expression inside empty function will lead to generate fatal error.

Example Problem Solution:

Wrong
if(empty(trim($testimony))) echo “Empty”; else echo “Not Empty”;

Correct
$testimony = trim($testimony);
if(empty($testimony)) echo “Empty”; else echo “Not Empty”;

Wrong
if(empty($bobj->get_results(‘post’)) { // Processing Code }

Correct
$tmp = $bobj->get_results(‘post’);
if(empty($tmp)) { // Processing Code }

This is common error occur due to wrong permission setting in Gallery2 data directory.? During module uninstall, gallery2 restore directory permission and other changes as it was before the module installation. This feature sometime break gallery directory permission and directory does not work.? See Image bellow for exact error description.

Solution:

Try changing gallery data directory “/g2data” permission to 777. If this does not fix your problem then try changing permission to “/g2data/smarty/templates_c“. After this step delete all content including directory inside “/g2data/smarty/templates_c” directory. This should fix ERROR_PLATFORM_FAILURE problem.
