Pages Updates not Visible and 404 Errors for pages

Hi, I’m getting 404 errors for some of my pages. I’ve done the fixes suggested in other posts (htaccess has the code required, and I’ve saved the permilinks page without making changes), but nothing has fixed it.
Also, I’m changing pages and updating them, but the changes aren’t visible… both on the live site (when the pages do work) or by clicking the preview button.

Hello there,

I am sorry to hear the issue you’re having. Have you tried this solution? Actually, 404 error isn’t theme-related issue, but it’s server side matter. To verify, try to switch to the default WordPress theme. For quick fix, I’d recommend you to contact your hosting support department.
