Yesterday I created a phpBB forum from the "one click installer" feature. I chose the 'Easy' interface option and I chose the name "forum." and it was successfully created.
For a reason I had to delete the forum, so I went to the interface and chose to delete the forum. Now I want to create it again under the same subdomain of course, but I can't do that anymore. It is telling me:
Invalid Domain: forum. is already being used in our system!
But actually it was deleted!
Somebody help me please...
