Your software
My Mautic version is: 4
My PHP version is: 7.4.28
My Database type and version is: mariadb

Your problem
My problem is: cannot access mautic anymore…
If I try to access mautic using ip address I get error 500…

These errors are showing in the log:
Looked at APACHE log:

I do not have this file in cache, I did clear my cache so this might be the reason…

What can I do to fix this error… why is this triggering and how can I regain mautic access?

I see the issue, but how can I fix??

Thank you,

Cache needs to be writable by your apache user (typically www-data). Run this after you are done editing mautic config

chown -R www-data: var/cache
chmod -R u+w var/cache

And in addition to cache write permissions are also necessary on following folders:

  • var/logs
  • var/tmp
  • var/spool
  • app/config/local.php
  • media/files
  • media/images
