ad.js:30 Uncaught Error building tag, no sizes seem to work.
For my ad zone. In this case on a phone, the size of the div is 1694x152. What am I doing wrong?
Looping back to respond to this unanswered question. For AdPlugg Network ads. AdPlugg will work to determine the best ad sizes to include when your inventory is posted to the exchange. This is based on the size of the Zone div on the page, the sizes that are supported on the ad exchange and any size restrictions that you've set on your Zone (via the Min Width, Max Width, Min Height and Max Height fields). The "no sizes seem to work" error means that there weren't any ad sizes that would work where the tag was served (based on the aforementioned div size, sizes supported by the exchange, and rules set on your Zone).
If the Ad Tag div is 1694x152 as you said, then at least a 728x90 ("Leaderboard") should work (and is generally supported on all exchanges). So likely you have a size restriction (Min Width, Max Width, Min Height and/or Max Height) in your Zone settings that is prohibiting it.
