after upgrading from 2.3.4 to 2.3.7 (with some difficulties, see below) i am stuck with another issue: I can not create user.
It is obviously the bug described in https://mylittleforum.net/forum/index.php?id=9550.
There is a fix from Micha, but I could not figure out what to do for getting that fix into my 2.3.7.
Yes, I intend to upgrade to 2.4.19, but for some special reasons can not do it right now. So, should I edit an php file or is there another (better) possibility?
