Please take a look at this thread here: http://wordpress.org/support/topic/admin-ajaxphp-chandlerapply-is-not-a-function?replies=2#post-4329483
I have followed that guys advice and disabled every single plugin and tested if the issue was still present. Upon disabling pagebuilder, the page refresh after selecting an image from the media library suddenly worked again.
To verify this, I have then enabled all other plugins again, and it still worked. Then I enabled pagebuilder again, and the c.handler.apply function broke again.
How does it come that pagebuilder breaks this function? For me it is nut such an issue, but for my cliënt it can be very helpful to see and verify that he selected the correct image. Is there anything we can do to make this function compatible with pagebuilder?
Thx in advance!
