askvortsov I would recommend adding a listener for extension enabled/disabled that clears the cache as a local extender in y'all skeleton.
I will open a new thread and ask how it can be done, since I don't know PHP/how to extend Flarum
clarkwinkelmann Flarum should already natively clear the Flarum cache on extension enable/disable, no?
No, AFAIK that was never the case (not sure if beta.16 changed this)
Or maybe it has something to do with browser
That's very unlikely, since the error is logged server-side, and after cache is cleared, you can access the forum without any problems, without the need to also clear browser cache
