Hi @lisaz . It might be your current Wordpress Theme issue overriding the wpforo layout? To test this possibility, try activating a basic Wordpress Theme like, Wordpress "twenty-nineteen", or "Storefront"
Go to WP Dashboard > Appearance > Themes
then refresh your page on the front end (Control F5) and see if that brings back your wpForo with the wpForo format and layout. If you see the wpForo theme layout again, then it might be your current Wordpress Theme.
If you provide your website name, the community or perhaps the wpForo team can also take a look. Good luck and God bless you. 🙂
I'm just a member here who used to be a newbie.
The case: When I actually put my keyboard where my forum is, and became #172. Can you imagine if you had to build this forum yourself? How kind and patient will you be? The best way to say thank you is say it, write it, and then head on over at Wordpress plugin page and rate wpForo 5 stars - by clicking here.
