How to stop this from happening in my forum?
 

Please help.

I created a post.

Clicked "Submit"

and the next page to load says this:

I can see that the post successfully displays, and it's there after I go back to the forum's home page, but I don't want the user to experience all this garbage when they click "submit"

The problem occurs as a moderator and a regular user.

Please help me solve this problem.

Thank you ever so much,

That's from an add-on.
If you deactivate the pluginsystem you'll see that this doesn't happen anymore.

You could check which add-on have plugins at hook newpost_process and threadfpdata_presave.

i'm pretty new at this but I think I follow you.

The only thing I installed besides my custom skin is the VBSEO. Would this be considered an "add-on" or would the skin i'm using be it?

Thank you for your help BTW. I really appreciate it being a nooB. =)

Anything listed under admincp > plugins & products > manage products or plugin manager pages is considered a plugin.
