[2] file_exists(): open_basedir restriction in effect. File(/themes/theme_name/modules/index.php/translations/es.php) is not within the allowed path(s): (/home/username:/usr/lib/php:/usr/php4/lib/php:/usr/local/lib/php:/usr/local/php4/lib/php:/tmp)


Open /classes/Language.php file, and change line 381:

if ($module !== '.' && $module != '..' && $module !== '.svn' && file_exists($tPath_from.'modules/'.$module.'/translations/'.(string)$iso_from.'.php'))

if ($module !== '.' && $module != '..' && $module !== '.svn' && @file_exists($tPath_from.'modules/'.$module.'/translations/'.(string)$iso_from.'.php'))
