Steps:

• Go to MAMP application >> Preferences (button) >> PHP (tab) >> Choose 5.3.1 or greater >> choose OK.

For Rochen or some other Joomla hosts similar to its setup

Steps:

• Create a php.ini file with the following:

magic_quotes_gpc = Off
extension=pdo.so
extension=pdo_mysql.so

• Put it in your Joomla 3 root. Then change the htaccess.txt in your Joomla 3 root to .htaccess. Add the following lines to the .htaccess file (at the top) :

<IfModule mod_suphp.c>
  suPHP_ConfigPath /home/myusername/public_html/yourJ3folder
  <Files php.ini>
    order allow,deny
    deny from all
  </Files>
</IfModule>

Change "myusername" and "yourJ3folder" to your respective folders.

.htaccess for some hosts

For some hosts, add "php_flag magic_quotes_gpc off" to the .htaccess file
