What should my .htaccess file look like if my account is on a suPHP server?
You should remove the lines that begin with “php_value” and “php_flag”. You will need to move these files to a file named php.ini and upload php.ini into your public_html directory. Then, add the following line into the .htaccess file in your public_html:

suPHP_ConfigPath /home/username/public_html

where “username” is your cPanel username. You will need to remove php_value and php_flag from ALL .htaccess files you may have. However, you only need to add the suPHP_ConfigPath line in the .htaccess file in your public_html directory only.

Please note that you will need to change the format of your php_value and php_flag lines into the php.ini format. (Refer to the FAQ entry on how your php.ini file should be formatted).
