Server error 500 is driving me crazy.

milanisapparel · March 7, 2018

i all,

So since yesterday we randomly are experiencing server 500 errors. I have been searching for the past 2 days and it is driving me insane I cannot find the issue. When debugging is enabled, everything works fine. When disabled we get internal servers 500 errors in the backend, but also in the front end.

When trying to clear cache we get permission errors even though file permission are correct, i triple checked (755 folders/644 files)
Clear cache error

Whoops, looks like something went wrong.

When I try to disable debugging, under advanced parameters -> Smarty cache I get the error:

Error: Could not write to file. Make sure that the correct permissions are set on the file /sites/milanisapparel.com/www/config/defines.inc.php

What i already have tried:

-Delete and regenerate HTacess file
-Compile and cache folders are empty with just the index.php (/www/cache/smarty/cache and /www/cache/smarty/compile
-Restore backup, older backups have the same problem
-Disabled modules
-Deleted modules

-Checked all file permission, folders are set 755 and files 644.

If anyone has any idea it would be much appreciated.

Try to delete

/sites/milanisapparel.com/www/app/cache/dev

and

/sites/milanisapparel.com/www/app/cache/prod

On side note to try to make test shop and try to upgrade to latest 1.7 and also try some PHP 7 version.

Ok I deleted the files inside the folders, errors persist.

When I try to disable debugging in backend I get:

2 errors 
Before being able to use this tool, you need to: <br />- Create a blank .htaccess in your root directory. <br />- Give it write permissions (CHMOD 666 on Unix system).

Now I can get back in the admin area when I turn debugging off, some pages/functions in backend still end up with Internal server errors. During checkout we also get the blank page when debugging is off(internal server error).

One possible cause is "ownership". It can happen that for the computer FTP and the Prestashop program are different users and that that gives problems. But this is the kind of things you should ask your hosting provider.
