Totally bizarre. I restarted in safe mode of Firefox, and it worked. So then I restarted Firefox again, not in safe mode and it still worked.
I’d restarted Firefox when I first found the problem, so something about restarting in Firefox in safe mode fixed. Bottom line, I don’t think it’s a MailChimp issue, but most likely a Firefox or add-in issue.
Thanks for the quick response!
I’m having the same issue. Please post if you come up with a solution! It seems that they created a new category of entry, it’s not a page, it’s not a regular post, it’s an event. But, I don’t know enough about wordpress to know how to have it show up as a post in the homepage.
