'Field "backurl" is mandatory'

[_Andrey]

Hello.
I encountered this bug after update to 6.4.0 today. Since there is no possibility to downgrade and absolutely no desire to upgrade up to alpha build (even if it is possible) maybe someone could tell me there is any chances to obtain patch for 6.4.0 that fixes this issue?

Resolved in development branch feature/ZBX-22401-6.4.
There's nothing to lose with testing out the changes, what are there .. https://git.zabbix.com/projects/ZBX/...rMenuPopup.php Make a copy of that original file and edit it... There's only couple of lines to change

I installed an update up to 6.4.1 from official repo but it didn't solve the problem (I assume, that this patch hasn't been included in release?). So I applied a diff from zabbix git link that you provided to me and it helped, thanks alot.
