Go to wpForo BOARD settings and see what is the slug (permalink). Forums or Community?

Also see the PAGE ID of the forum page. The SLUG is your FORUM page with the [ wpforo ] shortcode. Check the PAGE ID? Is it correct?

After fixing all that, do a soft and hard flush of permalinks in wpForo Overview.

fixed it not sure why the page id was set to 29 but changed it back, now it works

Great news, still W3TC is active.

It should be deactivated now, I have uninstalled it because using a different one

I have no idea what this is but it MUST be removed at least from wpfor page(s).
