Thanks!
I’ll test these fixes out and see what happens.
Have you figured this out. I seem to be experiencing quite a similar issue. the website is laymission.net
The 404 errors seem to disappear for a short amount of time when permalinks are re-saved, but it’s only a temporary fix.
If it helps, am using the theme “University” and the backbone to the website is Learndash LMS
Please help.
