Alright I understood that, and we had a series of spam bots, so I deleted quite a few, and now there are less actual members then total members. Is there a rebuild or something I have to carry out to fix this?
I think i have a similar issue, this is on version 1.4.2. When viewing the List All Users I see 27. In the member statistics box, the total members is 20. I don't have anyone banned and nobody is awaiting approval. I ran the rebuild cache for all options but that didn't change anything. Am I missing something?
