CiviCRM and the WordPress Pods plugin (since version 2.7.13) is incompatible due to Pods including marionette v3.3.1 for backbone, newer than CiviCRM's bundled marionette v1.0.3
CiviCRM and the WordPress Pods plugin – Custom Content Types and Fields (since version 2.7.13) is incompatible due to Pods including marionette v3.3.1 for backbone, newer than CiviCRM's bundled marionette v1.0.3
Erroring line in CiviCRM's js/view/crm.designer.js has been present for over 6 years, see js/view/crm.designer.js
Issue is that the v3 Marionette library that Pods loads does not provide the ItemView object.
Potentially could be solved by CiviCRM aliasing the Marionette object into the CRM namespace when Marionette is loaded, and then refactoring all CiviCRM code referencing Marionette to use this.
