**Your software** My Mautic version is: 5.1.1 My PHP version is: 8.2 My Database type and version is: **Your problem** My problem is: I can’t clear the cache. These errors are showing in the log: // Clearing the cache for the prod environment with debug false In FileLocator.php line 39: An empty file name is not valid to be located. cache:clear [–no-warmup] [–no-optional-warmers] Steps I have tried to fix the problem: Installed another instance of Mautic via composer and there it works. ---

Perhaps a permissions issue? If you are on a Linux system, try giving appropriate permissions to the cache directory before running `cache:clear` again: ```auto sudo chown -R www-data:www-data /path/to/mautic/var/cache sudo chmod -R 775 /path/to/mautic/var/cache ``` ---

Many thanks for your answer. Unfortunately no change after changing permissions. Same error. ---

I’d try `rm -rf /path/to/mautic/var/cache/prod/*` ---

It must have to do with composer. I just rolled back to the non-composer installation and now it works! ---

Could it be, that the error is because in the Configuration I did not enable: “Update Mautic through Composer [BETA]” ? I installed mautic 5 again via composer and now it works, so far. I could clear the cache and also update the plugins. ---

I got same issue and found that the issue was invalid plugin , therefore , I have removed the plugins and run again without any issue.
