I got an error message when I tried to log into the administration interface for a Joomla 3 site running on a Liquid Web hosted site.

The problem is corrected by adding a php.ini file to the root directory of the site and making a change to the .htaccess file. The changes are documented here:

http://docs.joomla.org/How_to_turn_off_magic_quotes_gpc_for_Joomla_3

In summary:

create a php.ini file in the root directory of your site and put in the following line in the file:

magic_quotes_gpc = off

Edit the .htaccess file for you site and add the following text to the start of the file. Replace "accountname" with the name of your hosting account.

<IfModule mod_suphp.c>
suPHP_ConfigPath /home/acountname/public_html/
<Files php.ini>
order allow,deny
deny from all
</Files>
</IfModule>
