Custom Post Types Permalinks

I am having a similar problem to https://www.ads-software.com/support/topic/custom-post-types-permalinks-404

I have a custom post type called “video.” All was working fine with my custom post rewrites when I had it like this:

In my theme’s functions.php register_post_type arguments I just had:

‘rewrite’ => true,

and in my permalinks I had it set up as /0/%postname%/

Everything was working fine with regular posts coming out like: sitename.com/0/post-name

and videos coming out like sitename.com/0/video/post-name

I was given a request by my supervisor to remove the “/0/” and the “/video/” from all URL’s so what I did was go back into my themes functions.php and replaced

‘rewrite’ => true, with

‘rewrite’ => array( ‘slug’ => ”, ‘with_front’ => true),

and then in my permalinks I replaced “/0/%postname%/” with just “/%postname%/”.

Now the regular posts are coming out as desired but the custom posts (videos) are all coming up 404.

—————————————

One other thing: If I just set the default in the permalink structure, the videos show up fine as:

sitename.com/?video=post-name

—————————————

Here’s something else –

If I change

‘rewrite’ => array( ‘slug’ => ”, ‘with_front’ => true), to

‘rewrite’ => array( ‘slug’ => ”, ‘with_front’ => false),

and then in my permalinks I replaced “/%postname%/” with “/blog/%postname%/”

Then the custom video posts show up

as sitename.com/post-name (as desired)

but the regular posts then become 404.

Any thoughts out there on this puzzle?
