Hey man, a couple things. First, the plugin white-screens the site when you install it because:
[02-Jun-2016 06:29:23 UTC] PHP Fatal error: Call to undefined function url_encode() in .../wp-content/plugins/cmb2-admin-extension/cmb2-admin-extension.php on line 156
Also, the CMB2_LOADED
constant is no longer true
, but instead the priority value. So checking explicitly for true
will cause it to fail.
