Integrity Check - EXTRA_FILE

Nextcloud version (eg, 12.0.2): 16.0.4
Operating system and version (eg, Ubuntu 17.04): FreeNAS Jail
Apache or nginx version (eg, Apache 2.4.25):
PHP version (eg, 7.1): 7.2

I keep getting this integrity check error, I believe since I first upgraded to 16.x. I don’t even have the news plugin installed and I cannot find these files in my nextcloud install folder (/usr/local/www/apache24/data/nextcloud/ for FreeNAS/BSD)

Technical information
=====================
The following list covers which files have failed the integrity check. Please read
the previous linked documentation to learn more about the errors and how to fix

The messages are generated because Nextcloud checks the whole directory and file structure starting from the Nextcloud root directory. Independently if you’ve activated the news app or not, the files seem to exist in that structure.
Check the “apps_paths” parameter in your Nextcloud config.php file for the exact path(es).

Thanks, but I have I have no app_paths in my config file.

Ok, then you should check if an apps folder exists within your Nextcloud root, where all apps are stored.
