http status code 404 - Top Level pages in wordpress giving 404, but child pages working fine -

Actually everything except top level pages (for example category, archives, single post, custom post type, etc.) works fine. .)

I have 3 custom post types and 4 custom taxonomies (each custom taxonomy is related to a post type, respectively, and another classification is linked to all post types). In addition, custom taxonomies has a recycled set, which is to show the word and not classify itself.

Any thoughts as to why this is happening?

Update:

After doing this, why was this happening shortly after watching this, I found out the problem in the reading settings, my first page Was set to appear in the form, and when I changed it back to the default, everything was fine

This can also be resolved by changing the permalink settings, permalink settings for you to save the plane and settings You can change, then check your pages. It will be shown till now, return your permanent settings to once done, rename and save settings. This way your pages will be shown correctly.
