I'm not seeing any issues on my side, and given that there have been no other complaints about it today (forgot to check out the forum, as I was busy working on more 'dlc to episode' conversions, I HATE THE STEAM DATABASE!!! Now 7500 movies & show episodes in it!), I suspect it was a problem on your side...? Can you try again?
Well I don't know, when I click "Send Offer" I get redirected to the final offer, with 'edit' and 'cancel' buttons on it. What happens when you click it? Does it load a new page? What does it have? The offer creation page or the final offer page?
Oh... So you mean it behaves like when you click 'Preview'...? @_@
PS: anyone else care to chip in..? I really, really don't want to tweak my code to remove my admin rights on that page.. Yes, I'll do it eventually, but... I still think it's a problem that would be reported by more than one person if it was the same for everyone.
Right click, Inspect Element, then there's a 'Console' tab to click. Make sure to keep the log (by default, IIRC, it empties the log when you move on to another page, e.g. by clicking on a button.)
