Ooof! Had to roll back to 1.7.7
No errors on update. Caches cleared. No addons on this forum. No JS errors in console. Plugins deactivated/activated - no difference. All custom CSS removed, no difference. Perhaps a theme incompatibility - Generate Press?
BTW, make sure you don't use old wpForo addons, all old addons should be updated.
And makes sure you've clicked this button right after the wpForo update:
There are no customizations or addons on this board. One other problem, one cannot edit the page where the forum shortcode is - this throws many JS errors, see below. No such problems on 1.7.7

Mot sure if it helps but I'm running GeneratePress Pro theme and updated top wpforo 1.8.0 and it went smoothly. That would suggest nothing much wrong with theme compatability
Only problem I'm left with is polls is not working, it won't update to 1.0.6. That's nothing to do with this site and Gvectors are looking into it. All other wpforo add-ons updated OK and appear to be working.
Yep did that and it worked.
