I have/had a bug on my monthly calendar view displaying as though it was in a widget. I started the topic here but didn’t get back in time before the thread was closed.
Bug on Calendar or Monthly view after update
I went through the theme and plugin and the issue is with W3 Total cache. I found this thread and tried the solution, but it just causes different problems.
TEC Pro exclusions for W3TC minification of JS/CSS
The site is terribly slow and the host provider insists I need to use a caching plugin so I need to see if I can find a work-around.
The problem that occurs with the minify on manual is the hover/over boxes don’t appear when you hover you mouse over an event in monthly view. The boxes display beneath the event causing the entire calendar to be unreadable.
