@baby-gnu do you have a PHP object caching in place? If so, can you try to clear caches? Can you also check if includes/functions.php exists?

[baby-gnu]

I purged the cache and updated to 4.1.1 and did not receive an error mail.

So it seems to work for you now @baby-gnu ?

[baby-gnu]

yes.

Then I will close this for now! Please re-open if you see the error again!
