# jQuery(…).sortable is not a function

 * I’ve just rolled a development site to a staging server and suddenly the admin
   Constant Contact form edit page is throwing this error. The dev and staging servers
   are identical, and I do not have the problem on the dev server. The functionality*
   works* on the front end of the staging server, but I can’t make any changes to
   the settings now.
 * Anyone have any ideas?

 * Are you familiar with the SCRIPT_DEBUG constant available for WordPress? We would
   be curious to see more information for this case, and that constant will use 
   the non-minified copies of js files, and provide a better call stack.

 * Thanks for the quick reply – turning on all debugging options gives this in output:
 * `Fatal error: Declaration of CMB2_Type_Wysiwyg::render() must be compatible with
   CMB2_Type_Textarea::render($args = Array) in /path-to-content/wp-content/plugins/
   constant-contact-forms/vendor/CMB2/includes/types/CMB2_Type_Wysiwyg.php on line
   16`
 * And continues to throw the jQuery(…).sortable is not a function error, reporting
   jQuery v=1.12.4 and tinymce-shortcode-script.js v=5.4.7.2

 * This occurs when the bundled version of CMB2 is not up-to-date and the server
   is on PHP 7.2+. Please read here for more on the matter: [https://wordpress.org/support/topic/fatal-error-cmb2_type_colorpicker-line-13/](https://wordpress.org/support/topic/fatal-error-cmb2_type_colorpicker-line-13/)

 * There is a discrepancy in PHP versions – I hadn’t noticed that. I assume [@constantcontact](https://wordpress.org/support/users/constantcontact/)
   is working on this?

 * Version 1.3.7 will include the updated copy of CMB2, but we have not yet released
   it yet. Hopefully soon.
 * Here’s an early release copy of what we have in 1.3.7 at the present moment:

 * Hopefully this resolves that portion of the issue, and we can resume the jQuery
   aspect.

 * Did the update fix all the issues? Not just the fatal error part?
 * Other than that, it sounds like maybe the two servers were on different PHP versions
   and that’s where the conflict came from.

 * Update fixed the fatal error, which in turn fixed the jQuery error. The site 
   appears to be good to go – thank you again!
