No, I never got it to work.
I’m running these scripts:
Contact Form 7
Hide Comments
Limit Login Attempts
Simple Calendar
Theme Test Drive
Ultimate TinyMCE
I don’t know if any of them does any caching.
Found the culprit… A UL tag in my theme had a 50px margin.
Never mind on the “AddThis” Div, that was actually in my theme. I commented the code out of the theme file.
Also, while doing some testing, the calendar shows up correctly with the “Twenty Fifteen” theme. So I’m looking at my theme to see what’s causing problems. This is challenging, as I’m not a strong coder.
