Try to disable it like described here https://una.io/cmts.php?sys=bx_forum&id=1440&cmt_id=5458 how it will work without it.
No, it should be fine.
When I add it, I get a 500 server error when I try to access Studio.
Thanks for checking my server, LeonidS. So far we know, that I have to talk to my server host, since I run UNA on a shared virtual server environment, that might prevent modules from functioning as expected.
