Esmi, and all –
So I deactivated all but four of the plugins. Then before I deactivated those essential last plugins, I switched in live preview mode to the Twenty Fourteen and Twenty Thirteen themes. Without saving or activating them, the issue was gone in the live preview.
I haven’t tried resetting the plugins folder yet. Is that step and/or deactivating those last four plugins worth it, if it seems to be a themes issue?
Also, what should I try next, if it has to do with the theme? It seems weird that it is showing up on this one artist page, but not the other ones.
For now I’m going to try switching to a new theme, saving, and switching back. That didn’t help. Other thoughts to try?
