Since vBulletin 3.7.x, a new security feature has been added to fend of spambots. While this is great, it also keeps hwbot from editing posts.
We are working hard on a proper fix, but for those who can not wait, there is a way to solve it manually. You can enter the secret security token manually, something that until now only was necessary for InvisionPB users.
The vBulletin mechanism to fend of bots is now working in a development version of the hwbot engine. Even better, InvisionPB forums should be fully working now too, without the need of manually entering security keys.
If you use vBulletin v3.7, please try switching to “VBB 3.7” in your forum configuration on our test server. The bots should start working immediately.
