XF 1.2 Not able to post as editor not loading


i had disabled all the add ons and then it worked.. then 1 by 1 i had added them.. and found the error.. it was in Advertisement manager.. i had 3 ads in it.. the 3 ad was created today as below breadcrumb ad..
And this ad was creating the issue..

I have removed that ad and now its working fine..

Thanks for your help
