"Downgrading is not supported" after upgrading from 11.0.0 to 11.0.1

Hi there,

I just finished upgrading my nextcloud instance to 11.0.1 I receive the following error when trying to access my cloud:

Downgrading is not supported and is likely to cause unpredictable issues (from to

This error confuses me a bit since I have installed neither of the two versions. I have searched through the forum here and came across a number of similar error messages. All these topics could be solved by manually changing the version number in the config file (in my case to However, it as well fixes the issue for me, but when I then login I get a notification that I am not using the most recent version.
Since I have not changed anything in the PHP files by hand I am wondering what I can do to omit the issue and upgrade to the most recent version?

Also a note on how I do my upgrades: I am not using the built in updater because I once lost all my data using it back in owncloud times. I now always download the most recent version of NC and symlink the data and config folders into the extraced source source folder. After running the the upgrade method of “occ” normally everything works fine.

So just in case anybody is coming across the same issue: The reason why nextcloud threw the error mentioned above, that it seemed that the old version number had been cached in whatever php cache.
A simple service php-fpm restart seemed to have cleared the cache and it’s working now.
