Yeah, backfill (Adsense) ads are okay. It’s DFP ads that are the problem when there is custom artwork. It renders the container as 290 wide and cuts off the ad.
Hmm that’s very odd. The plugin isn’t aware of what type of ad is rendered. That’s entirely up to DFP. Are the plugin’s div’s the correct size? div.google-dfp-label, div-gpt-ad-topic-list-top.
