The SEO control box from Rank Math is not appearing as it should. This problem specifically occurs with Custom Post Types (CPTs) that have a taxonomy (category) assigned. I have used Metabox to create these CPTs.
For other types of posts, including native posts with categories, the Rank Math SEO control box is functioning properly. It also works correctly for CPTs that do not have a taxonomy assigned.
The issue arises exclusively with CPTs that have a taxonomy; in these cases, the Rank Math SEO control box fails to appear. I've attempted to resolve this by deactivating other plugins, but this hasn’t been successful.
Attached is a screenshot depicting the error I encountered. As I lack expertise in coding, any assistance would be greatly appreciated.
Thanks
