Error 500

[HQ Level]

Hello.

I'm having some problems with my website, after I manually translated some fields from the Prestashop blog module 1.7.

Now, I'm getting an Error 500, and I suddenly I was logged out , and now I cannot acces my admin panel.

I edited the file define.ini.php,  and changed define('_ps_mode_dev_' false) to define('_ps_mode_dev_' true) and i was able to get some explanations but i still cannot acces the admin panel.

I attached some printscreens, and I'm hoping that somebody is able to help me.

As the error is coming from a cache file try to rename /var/cache to /var/cache_old and reload the page.
