Hey Guys,
I’m sorry it took me a while to respond. I wanted to make sure what was going on. There are some times when other plugins will introduce JavaScript that conflicts with the Editorial Calendar. Most of the time there isn’t much the calendar can do about it except contact the creator of the other plugin.
WordPress 3.1 made a change to the way JavaScript is loaded on the calendar page which made these conflicts more likely. I have released version 1.3.3 of the calendar which loads the JavaScript a little differently and will hopefully fix this issue.
Thanks for sticking with us and please let me know if this new version resolves your problem.
Thank you,
Zack
