Mark Hesketh Posted March 16, 2012 Share Posted March 16, 2012 Sounds like theres a PHP problem somewhere, maybe from a module. Try enabling debugging and you should get an error message where the problem is happening: In config/config.inc.php line 28: /* Debug only */ @ini_set('display_errors', 'off'); define('_PS_DEBUG_SQL_', false); (More info on Displaying prestashop error messages here) Change these to on and true, reload the page and you should see where the problem is. Paste that here and I'll try to help, Mark Link to comment Share on other sites More sharing options...
