Hi
Of course it was false. I cannot leave 404 page errors on my site for weeks…
I have to switch it off as it doesn’t work. I have 404 errors again on all portfolio pages.
I need to switch this off as I am showing clients the portfolios.
the issue is not that it was switched off. It’s that it isn’t working when it is switched on. 🙂
Once you change the rewrite settings, you will need to set your permalinks back to default, and then to the original option again. This is something WordPress needs in order to flush the rewrite rules.
