Hi, make sure files are right ownership: if the webserver runs as www-data, then: chown -R www-data:www-data /var/www/html/mautic/ Also: check rights: chmod -R 755 /var/www/html/mautic/ You can also rebuild cache and see if you get errors. If you are root, you can run it as the web user: sudo -u www-data php /var/www/html/mautic/app/console cache:clear Good luck ---

I have Mautic in a shared webhost, permissions of mautic installation are rwx --x — for the main folder and rwx r-x r-x for the subfolders ---

Find the directory mautic is installed in, and find the owner of that directory, for example, if mautic is installed under: **/home/username/public\_html/mautic** I’ll find the owner using: > ls -l /home/ **username** /public\_html/mautic If you check that, then it might have been replaced with the root user cos of the way you cleared the cache, so, just change it to www-data as that is the default web server user, at least on Ubuntu, change it using: > chown -R www-data:www-data /home/ **username** /public\_html/mautic Now, whenever you want to clear your cache, use the app/console and run it as www-data, e.g: > sudo -u www-data php /home/ **username** /public\_html/mautic/app/console cache:clear _Note: I am assuming, mautic is installed under **/home/username/public\_html/mautic** , so you might wanna adjust that to wherever mautic is installed._ ---

Hi guys, it is a shared web host, I can’t use the shell. Mautic is installed in a subdomain…it always worked, I don’t understand why deleting the cache folder could cause this sort of issues… ---

Today I cleared the cache again and it worked. I didn’t need to change any file permission No sense in this…
