**Your software**  
My Mautic version is: 3.3.2  
My PHP version is: 7.4  
My Database type and version is: 10.4.18-MariaDB

**Your problem**  
My problem is:  
I can not delete my cache using command line and I got an error and when I delete /var/cache/\* mautic is broken!  
These errors are showing in the log:  
Type error: Argument 1 passed to Symfony\Component\Config\Loader\LoaderResolver::addLoader() must implement interfa  
ce Symfony\Component\Config\Loader\LoaderInterface, instance of Symfony\Component\Translation\Dumper\XliffFileDumpe

Hi there,

what does  
`ls -la <your mautic homedir>/var/cache/`  
show for you?

Thanks
