Any Hints?

You likely have outdated templates that need to be resolved. Specifically I suspect your core_fa.less template is outdated.

FWIW we'd strongly advise that you do not edit this template in future for this very reason.

If it is modified in your style provided to you by whoever designed your style then you should raise this with them.

Problem is fixed by reseting core_fa.less - Mainforum upgradet then without any Problems.

Ideally avoid modifying any template that begin with setup_ or core_.

glad to know i need to prepare for this upgrade....

we still need to edit this core_fa.less, just to get the brands icons to display....i made a thread about it a while ago, but not sure i was understood as there seemed to be a few related issues...

i would prefer to have it fixed in the core coding and not have to worry about booby traps like this one, any suggestion here?

No changes are required to support brand icons or any other icon type in XF. If you are experiencing issues with that you probably need to make a separate thread to try and explain the issue again.

On this very forum you can see Brand icons in various places, including at the bottom of this thread.

That should work by default in XF without any code changes.
