We’re running this on WP Engine, and having massive issues with any jQuery on Event Espresso. Since 3.6 uses jQuery 1.10…, Espresso is having issues with any live() function usage. We also have to set concatenation off in WordPress, which causes issues with our other plugins.

We’ve already spent too much time trying to troubleshoot it… do you have a quick solution?

Hi Davin,

It sounds like you’re on an older version of Event Espresso. The live() method has been removed and replaced with the on() method from Event Espresso a few versions back in order to be compatible with the newer version of jQuery that ships with WP.

Updating to the latest version of Event Espresso should help.

BTW, WP 3.6 includes the jQuery migrate plugin, so as long as it’s enqueued there shouldn’t be any problems with using live().

I’ve had similar issues with admin script concatenation on one server that I test on in the WP admin. I think what happens is some servers can only handle x number of scripts being concatenated, and with every major version of WP that gets released a few more get scripts added so that’s when you notice it breaking.
