Can't use advance edit options in thread

[Mgale]

Hi!
I don't know if this is a bug or if I should post it somewhere else.

A few weeks ago I created a thread here in Ownedcore. I'm able to edit it using the editor that pops up when I click on the 'edit post' button, but when I click on 'go advanced' it redirects me to a Vbulletin error message that says

You do not have enough CoreCoins to edit thread title

I've tried clicking the 'go advanced' button leaving the original title, as well as after clicking the 'reset fields' near the 'change title' option. I've tried leaving the title empty (just in case it works), but no matter what I do, the error message keeps showing when I try to use the editing advanced options.

Any help would be apreciated.

ps: just to make clear, I don't want to change the thread title. I just want to use the advanced editing options.
