I have been trying to fix this issue myself but have not been able to as of yet. The navigation of the Events+ calendar is not working using the X theme from Themeco. I came across this for a different theme, but it looks like the same kind of issue. Unfortunately the fix is a bit different. Switching themes is not an option and I would like to solve this in a way that would be a one-time fix (child theme or something, so updates don't make this problem appear again). I currently can't provide the site, but I can send the theme once directed how to do so.
Any assistance is greatly appreciated. Thanks.
