vBulletin 3.8.4 Can Not Read Sent PM's

[gle041]

This seems to affect ever user. When viewing the PM inbox, if you select 'Sent Items' in the drop down and then press 'Go', it tried to load but does not. I've tried several times and I just get a blank page. Is this an issue with the database? What can be done to repair this?

Thanks in advanced.

disable plugins+products, try again. I doubt its a database issue as you can see your inbox ok.
