Having the same issue with a site I recently took over working on. It appears that it’s related to jQuery and a plugin that’s trying to implement an older version manually (from what I’ve read but not tested on my site). I’m not sure where to start at the moment, but i’m hoping that it’s a simple fix.
The first page shows up just fine (current month), but going back and forth give me the same error as devpaq. I’ve tried to adjust the settings but nothing in there seems to help (long shot anyway).
My site uses a handful of plugins, with the Cherry Plugin being the biggest one. I have it updated to the latest release (Version 1.2.7). WordPress is also on the latest version(Version 4.4.2). Not sure if it’s related to Cherry or another plugin.
I also came across a plugin that is supposed to be able to implement jQuery manually, but some of the reviewers said that it took down their site and they had to manually SSH into the site to remove it. Not risking that.
