I’ve seen this topic around on the WordPress forums, but the answer seems to be that the Yoast plugin was causing the problem. I don’t have that, so I’m wondering if there is something in the GP add-ons that could cause this or if I’m just doing something wrong. The problem that when trying to scale an image within WordPress — no matter what number I use to start scaling down the image, the other number comes up as NaN, which I believe stands for “not a number”? I hope I didn’t miss the answer to this because it seems to be a common problem. Just downloaded WordPress 4.7, but the problem was occurring before that. Enjoying the Exhibit child theme very much. Thanks.
