HTTP Error 500 when loading login page fpr Prestashop back shop

[Wullie]

Hello,

I have a problem.

I tried to load the login page for Prestashop back office and get HTTP ERROR 500.

My website is working fine but I simply can't login to back office.

I now can't login to back office but I have access to cPanel.

Please, can anyone help?

The error is:

[21-Jun-2020 16:45:13 UTC] PHP Fatal error: require(): Failed opening required '/home/bigwullie/public_html/var/cache/prod/Container9mkpjeg/removed-ids.php' (include_path='/home/bigwullie/public_html/vendor/pear/pear_exception:/home/bigwullie/public_html/vendor/pear/console_getopt:/home/bigwullie/public_html/vendor/pear/pear-core-minimal/src:/home/bigwullie/public_html/vendor/pear/archive_tar:.:/opt/alt/php72/usr/share/pear') in /home/bigwullie/public_html/var/cache/prod/Container9mkpjeg/appProdProjectContainer.php on line 1614

Thanks in advance

To my knowledge  the error is included in my post.

Thanks for your reply.

I have access via cPanel but not via the Prestashop login page as described.

Wullie, whats your Prestashop version?

It's obvious the issue is on cache plate. Not sure if deleting everything inside /cache should improve the situation.

I was looking in google for "clean prestashop cache manually", but I need your version to be sure nothing gets broken

Version 1.7

The website actually works fine....just lost access to back office. I'm a newbie and I think I have 3 choices

1) Research and resolve the issue.

2) Try rollong back, I think, the /var/cache using Jetbackup

3) I have another Prestashop almost identical...I thought as a last resort...just delete the whole website and import the files from the almost identical site using "softaculous". I really don't want to have to do that though.

 

Any help is much appreciated because I'm now reading up on PHP. I have found there are 2 commands "include" and "require" and the issue appears to be "required" related.

This file /home/bigwullie/public_html/var/cache/prod/Container9mkpjeg/removed-ids.php

doesn't exist.

/home/bigwullie/public_html/var/cache/prod/Container9mkpjeg/appProdProjectContainer.php on line 1614 is trying to include it, but it fails.

One way could be deleting everything inside /prod and /dev, but it's dangerous to recommend that with knowing close to nothing about your system.

1- ENABLE DEBUG MODE,  “config/defines.inc.php” file and open it and find the following code:

        if (!defined('_PS_MODE_DEV_')) {

            define('_PS_MODE_DEV_', TRUE);

        }

Save and try to visit your backoffice. Any change?

Thanks PHP Ninja,

You were correct.

Amazingly, I also found the solution in Prestashop forum via Google...."White page in Prestashop".

Surprisingly, as a newbie, I even found "removed-ids.php" on line 1614 as per the error log.

I'll carry on reading up on PHP as I guess it will do no harm to gain some knowledge.

Many thanks again.
