I received a complaint this morning that the “Next” month link on our event calendar wouldn’t load. I have disabled all other plugins and set the default template and the problem still persists. I have also deleted over 1000 expired events, with no fix. I also restarted the web server, PHP and Mysql services on the server.
It appears that the events are actually loading, but the loading “wheel” animation/overlay isn’t disappearing.
I had a similar issue with the next month link on the widget not working lat month, but it fixed itself.
