Mediavine Plugin Conflict Caused Rich Results Issues With Some Sites
https://www.searchenginejournal.comAccording to SEJ The Grow by Mediavine WordPress plugin had multiple bugs that interfered with other plugins, resulting in Yoast not outputting certain structured data elements. Some sites experienced a lack of rankings because of this issue and also resulted in Google dropping images from rich results for some sites.
For Grow users that are also using the WP Recipe Maker plugin, Grow versions 2.12.1 and 2.12.2 have the potential to impact rich snippets because of the way that data is output through Yoast in the head of pages. Version 2.12.3 release corrects this issue.
