Found a serious bug in Adwords.
I'm sure you have found the red message box telling you something about to not play with the browser back buttons. Well this problem usually solves it self after a while. But, have you ever found yourself in the situation when the red message box displays every time you try to access a campaign.
Well I've Sent a message to adword team about this problem yesterday, but today I found the solution that will unlock all the affected campaigns (yes not all campaigns are affected) and make them editable. The solution (drum roll) is to login to a second session in adwords and open a working campaing (create a temporary if not) then copy the shorcut from the non working campaing in the first session to the working campaign in the second session. Hit the return button. Volla! You got a working account again.
Important! Don't logout from the first session, just close the window then logout from the second session.
Sincerely
andla
