Does anyone know what is the reason of this issue ? _Steps I have tried to fix the problem_ : ---

Did you clear the cache and make sure permissions are right after the download ? ---

Okay, I did mention that in my blogpost, but It makes sense to read the whole thing: > This is usually a good advise, but running the command above can go terribly wrong. And this is because of the permissions. It’s super important that the right “person” is issuing the commands. Let me explain… And then I’m mentioning the part how to identify the right user and warmup the cache: > Once your permissions are already messed up, you can any time fix it. Go to your Mautic folder, and: `sudo -u www-data php /var/www/html/mautic/app/console cache:clear` ```auto find . -type f -not -perm 644 -exec chmod 644 {} + find . -type d -not -perm 755 -exec chmod 755 {} + chmod -R g+w var/cache/ var/logs/ app/config/ chmod -R g+w media/files/ media/images/ translations/ rm -rf var/cache/* ```
