Hey @ridha82

This can happen when one of the module files is cached in your web server, or even on the file system.

  • Try restarting the webserver
  • Try doing a “Force Update”
  • In CLI, delete composer.lock and run composer install

Hopefully it helps!

Hy @daftspunk

Thanks for your response, I ran composer install again and restarted the server, but the same error persists. The application is hosted on Cloudways.

Thanks

Ok, one more thing to try.

  1. Rename the modules directory to modules2
  2. Delete composer.lock
  3. Run composer update

See if it helps.

Since you are running Cloudways, please try purging the application cache:

Hey

I found the problem, it was caused by the plugin “Backend Skin” because it’s not compatible with v4.

Thanks
