SMF 2.1 RC3 Quote Problem

[Gaza07]

Ive just installed RC3 and Quote when replying to a message doesnt work it just says loading at the top of the screen ?
Is this a common problem ?

Open the browser console, try quoting, seeing there are any errors in the console.

I have re installed the RC3 Upgrade and its all running fine, it was an old bbcode mod that was causing the problem
