WordPress Yet Another Related Posts Plugin Admin Page Blank, Call to undefined function yarpp_reinforce()
While upgrading the WordPress plugins today for a WordPress site I manage today I ran into an issue with the YARPP (Yet Another Related Posts Plugin). This WP plugin provides links to like articles on each of the posts of the site. You can cross reference various variables such as titles, content, tags, and categories. After upgrading the YARPP plugin this afternoon I noticed issues during testing when the YARPP configuration page would not display via the WordPress admin. Below is information on the error that was located in the PHP error logs, what was initially attempted to resolve the issue, and what did resolve the issue with the YARPP settings page.
