My client drupal site stopped working suddenly and gave me this error Fatal error: Class 'RulesI18nStringController' not found in entity.i18n.inc on line 31
i checked the rules module and entity module and nothing seems to be messing.
I searched for a solution on the internet with no luck.
I have rules 7.x-2.2 and entity 7.x-1.0-rc3 but i can't login to the site so i can't access update.php to update the rules and entity modules to the latest versions "as it may fix this problem".
So can anybody help me find solve this problem?
PS: If you need any additional information about the problem just ask about it in the comments.
Thanks in advance for you all.
