It all were categories before but I went ahead and create all new categories with same name and then moved the forums over to it. After that I deleted all the categories that became forums after the upgrade.
it was an upgrade from Phorum to phpBB then to v1 which again upgraded to v2 so somewhere along the upgrade line I am sure it toggle the categories into forum. No big deal since I was able to fix it all an hour but I was hoping there was a toggle to switch between forum and category. I have a 3 millions posts and over 55K members forum.
As what I suspect but no biggie. When we are ready do the live import, we will just recreate those categories. I wish there was an importer for Phorum to Xenforo. :/ Any plan to add an Phorum importer to Xenforo soon?
