Can't close the box

Normally that indicates there is an incompatible jQuery library used like version 2+. Does the MaxButtons plugin load it’s own jQuery?

I have no clue. How to find out?

Can you share a link?

I’, also facing same problem, I could not close the fancybox, I’ve done the settings to show close button ‘Show the (X) close button’ and ‘Close FancyBox when overlay is clicked’.

As I said: “Normally that indicates there is an incompatible jQuery library used like version 2+.” … are you using a plugin or a theme that includes another jQuery version than the one that is included with WordPress? IF so, then Easy FancyBox is incompatible with that plugin or your theme.

@ravanh thanks for your reply, As you said, It was causing because of jQuery updater plugin. I’ve deactivated the plugin and it is working now.
