Call_user_func() expects parameter 1 to be a valid callback - Need your help!


I am using newest version of nextcloud. Now I have a big problem. I looked at my webspace and see a nextcloud.log file in /data whitch is growing extremly (15GB after one hour).

So I tryed many things, but only disabling the logging App stops it. Loglevel is 4 in config.

Now I take a look in PHP errorfile and see hundreds of these:

call_user_func() expects parameter 1 to be a valid callback, class ‘OC\Log\’ not found in /is/123/www/owncloud/lib/private/Server.php on line 424

If i // this in Server.php, another file makes this error.

Someone can help me with an idea for a noob in PHP. THANKS!
