Problem:
You are seeing Internal Server Errors in your browser when you view your web site.

You have recently added items to your .htaccess file that contain php_flag and/or php_value directives.

Example Errors:
Example items in your cPanel error log (cPanel > Error log) will be like:

Invalid command 'php_flag', perhaps mis-spelled or defined by a module not included in the server configuration

Invalid command 'php_value, perhaps mis-spelled or defined by a module not included in the server configuration

Reason:
The script you are using assumes that PHP is installed as a module. PHP is installed as a CGI on our servers. Your script should have documentation for how to install it on servers that run PHP as a CGI. This is sometimes referred to as PHP SuExec or SuPHP.

Solution:
Instead of adding these directives to your .htaccess file, add them into a file called php.ini and place this file in the same directory that your script runs in. Most often this will be public_html, but in some cases you will install your script in a subdirectory. Wherever your script runs, this is the place for your php.ini file. You will need to drop the "php_flag" and "php_value" prefix. You will also need to put an equals (=) sign between the setting and the value.

For example, if your script recommends these settings in a .htaccess file:

Code:
php_value upload_max_filesize 10M
php_value post_max_size 10M
php_value max_execution_time 60
Put them in a php.ini file instead. Here is the proper syntax:

Code:
upload_max_filesize = 10M
post_max_size = 10M
max_execution_time = 60
