Hello,

Hope you can help me solving the problem with my admin acces to my webstore. I was in the middle of work and then I lost internet connection for a couple of minutes and after that my backoffice acces doesn't work any more. 

This is an error that I get: HTTP500 Internal Sever Error

And this is an error log.

I tried to rename admin folder, delete all the cache and no luck.

I also changed php versions from current 7.1 to other version and still no luck.

Does anybody ever had such a problem and what could be a solution?

Thanks in advance.

I have a similar problem. I tried to load the login page for back office and I get HTTP ERROR 500.

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

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

William
