To Reproduce

Screenshots

Did you try having WeakAuras as the only enabled addon and everything else (especially something like ElvUI) disabled?

YEs, WA only addon enabled.
Which version of WeakAuras are you using?

2.14.2
Was it working in a previous version? If yes, which was the last good one?

WeakAuras.lua.zip
It was working yesterday (08/24/2019). Not sure what version that was.
Additional context

HERE

I uninstalled WA, reinstalled, logged in to WoW to verify wa interface worked, exited game, used backup to get WAs back, and now everything is working.

Edit: To be more specific I tried rolling back to 2.13 before completely uninstalling when it didn't work I uninstalled the whole addon as mentioned above. Only mentioning because someone said only uninstalling 2.14 didn't work for them.

I'm having this same problem. WA don't seem to display and I can't open the config window.

I've tried uninstalling and reinstalling as the OP but issue is still unresolved.

I had to roll back to 2.13.4 before it worked. Something in 12.14.1 and 12.14.2 breaks for me.

Same stuff here, after updating to 2.14.2 WA interface wont open, also most of WA's wont work. Tried reinstalling and rerolling, nothing works.
