Hi Iswitzer,
How is the user created content being created?
Fix Duplicates should work for any posts, pages, custom post types, etc, regardless of whether it’s created by the admin in the back end or a user submitting it via the front end somehow.
It won’t work for form submissions if they are not saved as a post, page or custom post type entry (ie if they are saved in a custom table).
If you can give me a little more information on how these posts were created (ie using which plugin, what steps you are trying, what happens, etc), then I’d be happy to investigate further.
Feel free to post information here or to contact me directly via my contact form.
