Duplicate Post Error Message

[Chad]

This post is a duplicate of a post that you have posted in the last five minutes. You will be redirected to that thread.

I get this suddenly when using the quick reply function, every time. Not sure why it suddenly started today.

The post does get posted, once properly but the message should not show up since I click submit only one time.

I ran this query too:

DELETE FROM session;

Result:
Affected Rows: 438 (0.0003s)

Duplicated this problem in Opera and Firefox.

I suspect there is a customization that is causing this. Try to reproduce it on a default style:

Admin CP -> Styles & Templates -> Style Manager -> [Add New Style]

Create a new style with no parent. Then click that style's name in the Style Manager to view your forum with that style.

If you still have the problem then try disabling your plugins:

Admin CP -> vBulletin Options -> Plugin/Hook System

Also run a file check to look for customized files:

Admin CP -> Maintenance -> Diagnostics -> Suspect File Versions
