Critical Error Duplicating Child Pages

    I tried to duplicate a page today using both “New Draft” and “Rewrite and Republish”. Both gave me a WP critical error.

    I then disabled all other plugins on the site and tried again. Same issue.

    After testing these actions on some pages, I saw that they worked fine. The pages that created the critical error were all pages that had a defined parent page. The problem is, after creating a new page, and giving that a parent, the problem did not occur.

    For some reason, it’s only an issue on some of my older pages on the site that have a parent page.

    Any ideas why that might happen?

    EDIT: Ok, I think I figured this out from the server logs. Those older pages were created when I was using the Elegant Themes plugin, Divi. This theme leaves a whole load of garbage in the post meta when you remove it, and maybe this is the cause?

    Hi @whistlerdan

    I am sorry to learn about the critical error you are facing. May I know if you still have Divi theme activated on your site?

    @whistlerdan yes, the cause is DIVI. You have to manually remove all records with the “ET_Core_PageResource” entry. In practice when you try to duplicate a post, it also duplicates all the records linked to that post, so since there is no more DIVI you get that error. I solved it by removing all the records from the database.
