RSTP Problems

Hi, I know I have RSTP problems in my network but Mikrotik is nog logging these changes or problems.
When I turn RSTP off in all bridges, than everything is working.
but that is not what I want.
Is there a way to enable logging for this?
Or Is there a other way to pinpoint the problem?
This problem is only in a CRS125 Switch.
I have several VLANS.
