1.7 Backend Error 500

[MrTouch]

I have an Issue, where i can't access to my backend anymore. Don't know what changes led to this. But entering the url to my backend results in a 500 Error. The server log looks like this:

The backend gets available as soon as I set _PS_MODE_DEV_ to true:

/* Debug only */
if (!defined('_PS_MODE_DEV_')) {
define('_PS_MODE_DEV_', true);
}

But I don't see any errors. When I set it to false I get Error 500 again.

The errors I see when I go to the front-page are:

 

 

EDIT:

After trying out different stuff to make it work again, I made it that only one error message appears when trying to enter the backend (with debug mode enabled)

 

But i can't find a solution to this problem by googling... I hope that this error message is known by somebody.

 

 

 

 

LAST EDIT:

I renamed the cache folder in /var/cache/ to /var/cache_old/ and suddenly it works.

This amounted to a deletion of the cache. It seems there was some bug in your cache.

Here’s one way that we’ve seen to be working for many:

- Login to your FTP account.

- Download .htaccess file.

- Add the line php_value memory_limit 512M in the file, and save

- Re-upload the file.

If you cannot fix it by this way, you can use another way like data migration. Ultimate Shopping cart migration is the easiest method I ever used for my clients. You can consider it,

 Hope it helps!
