Hi, after trying to update wpForo 1.9.9.1 to 2.0.8 all of my posts have disappeared.
I tested the update to v.2 a couple of times.
In one occasion I had similar issues to yours.
I first updated from 1.9.9.1 to 1.9.9.2 and then updated to version 2.x, this seems to have helped.
You might want to give this a try.
Thank you for the suggestion. I might give that a try. But first I'm still hoping for a solution that doesn't require me rolling back to a previous version.
It could be something the support team understands the cause of.
Go to wpForo > Boards, edit the current board and change the slug to tmp-board
Then go back to wpForo > Tools > Database Tables tab and click the [Solve Problems] button.
Then go to wpForo > Overview admin page, scroll down and click the [Delete All Caches] and [Hard Flush Permalinks] buttons
Thank you @robert
That does repair the forums.
There is an issue though, the login and registration URLs do not appear. I confirmed all login settings are enabled. If I look at the second forum with the slug tmp-board it does have login/registration links.
Furthermore, the board ID 0 and board ID 1 both share the same page ID. Is that a problem?
