Some other plugin is clobbering the admin-ajax request to retrieve the data.
No problem. Please let me know if I can mark this topic resolved.
Great! What was causing the issue? It could be useful information for other users. A vote for Slimstat would be a nice way to say thank you!
Honestly, I don’t know yet. I’m not javascript savvy to pick out which plugin’s callback is causing this issue so that I can target that. So, I’ll have to go through the mess of disabling plugins 1 by 1 until I finally figure out which one is causing this. It’ll be worse if I have to clear cache/cookies after each time I disable a plugin as that would require even more time to figure this out.
So, I’ll just save this problem for investigating during a holiday 🙂
