Major Issue! - PS1.5 - 500 Error Cannot access debug (tried everything)

[Aloud]

Hi folks,

 

My prestashop is on a vps that was rebooted and caused the website to crash

 

Now i have a 500 error and I cannot access debug to find out the issue.

 

I have changed 

 

@ini_set('display_errors', 'off')

to

@ini_set('display_errors', 'on')

Also config/defines.inc.php and change:

define('_PS_MODE_DEV_', false);

to

define('_PS_MODE_DEV_', true);

Still the screen is blank with a 500 error. I can upload a html file with some text to the server and it displays fine so i dont think the issue is server related.

Are there any other ways to access the debug/errors?

I dont know what to do with the site now

thanks in advance
