False size limit problem?

False size limit problem?

Hi-
 
Like the last user who reported on the same, or a similar bug, we have an older wiki (one that was set up in 2007, I think - ebrary.wiki.zoho.com) and when I tried to upload an attachment, I received a notice that we had exceeded our limit.  I went through each page of the wiki and deleted older attachments one page at a time and, after each page, I'd try again to upload the new attachment only to receive the same error notice.  In the process, I noticed that the "Disk space used" remained constant at 49 MB.  I've now deleted all attachments on the wiki and the "Disk space used" still says 49 MB used, and I still cannot upload attachments. 
 
I'd really like to get this fixed ASAP ... if nothing else I can't make the argument to the powers that be to upgrade the account until I can demonstrate the wiki's functionality in this project's workflow.
 
Thanks,
Jennifer
