Custom Code to integrate with feedzy RSS plugin Wordpress

We have a Wordpress site that uses RSS feeds and the Feedzy plugin. The user submits RSS feed urls to a CPT named Partners. On form submit the RSS feed url and user Id is then used to create a feed category and import the feeds to posts as a draft status with the current user as the post author.

The code has mostly been written by another developer but needs tweaking to run on this new staging site.
