It's maybe a more general problem.

The problem started at a go with two different installations of FA concerning 2 different non-profit NGOs.

On screen you see the little triangle that shows a problem there, but no explanation  what is the problem.

It worked for 2 years, suddenly it stopped in one day. Accountants are confused.

I changed php to 8.0 (8.1 works with fs similarly), that is when problem started. Now now I changed the php back to older version and it is ok now.
