After the current update, the calendar will not advance to the next month.
I am using WordPress 4.6.1, The Kleo Theme Version: 4.1.5, with Kleo Child theme.
All plugins are current.
The attached screenshot shows the page is trying to load, but it never does. If I deactivate TEC Pro, it works.
I reverted to TwentySixteen theme and deactivated the plugins, and it worked. The conflict is with the theme.
This is a great theme, but for now it is not usable for what I paid for.
