Reply To: 404 gives error in class.seo.php

I deactivated all the plugins but the problem still occurred. Something isn’t quite right. It’s really difficult to track down. I wrote out some backtrace output in PHP to find the offending issue, however it’s quite complicated to work out what is truly at fault.

I think I need to duplicate my entire website elsewhere by copying files and database… and then completely deconstruct it back to the basic core WordPress website. That way I can hopefully track down the exact issue.

I’m probably too new at using WordPress to get into the depths right now to fix this. It could take me two months to fix this and I haven’t got time, however I am concerned to leave it as it is. I guess it will have to remain a bug to fix in the future for now.
