Page title conflict with 404page plugin

Hi,

We’d been using Rank Math and Rank Math Pro along with 404page plugin without issues for weeks until we recently noticed that the 404 page’s title is being replaced with the title of whatever most recent post is. After deactivating/reactivating all plugins, I narrowed it down to Rank Math (both free and pro).

I looked over the Rank Math settings but could not find anything that would cause the titles to be changed.

I’ve also posted in the 404page support forum as I don’t know which plugin would be causing the problem.

All fix suggestions are welcome :).

Cheers,
Vinny
