Limited Support
Our team is currently on holiday, so support will be limited during this period. Response times may be slower than usual, and some inquiries may be delayed.
We appreciate your patience and understanding, and we’ll resume our usual support by the end of August.
Could it be that it doesn't show up due to the theme?
This is not an update issue, something wired is going on with your website. The forum was accessible 1 seconds ago, not it's not accessible. You've mixed forum page base URL and it seems you've created multiple pages.
Make sure you have only one page with [wpforo] shortcode in Dashboard > Pages admin page.
Make sure the page slug is the same Board Slug. Board slug can be found in Dashboard > wpForo > Boards > Edit Board admin page.
BTW, why I see the forum here?
