Post type rewrite breaks page url's

[garethgillman]

I have a post type which we rewrite a custom url using the following:

'slug' => '%kh_product_cat%',

It used to work but not sure when but it stopped working and although the post type url's work, the page url's don't.

Take that line out and the page url's work again, tested on a clean install of WP to make sure and get the same problem.

Has something been changed in WP recently which would affect this?

This trac instance is used to follow-up on confirmed bugs and improvement suggestions in WordPress core.
In this case, where you try to figure out what's happened on your site and how to fix it, the support forums at support.wordpress.org is a much better place.

I believe this is a WP bug, I have got help from other sources to see if it was my code causing the error and we can't find anything that will cause it.

I then used a brand new install of WP to test if it's something in my code that I may have missed and get the same result.

Not sure what else I can do, we have done everything we can to try and fix it in our code and got no where.

Where is this variable defined? Most WordPress variables have names that start with wp_.

[garethgillman]

The variable is defined in a filter which uses str_replace to change it, this works fine and removing the filter doesn't affect the above, as I said, adding the variable to the slug breaks the page permalinks across the site.

Giving this a bump as we are pretty sure this is a bug, we are fine with a temporary fix if it means we can get this working until the core team can find a solution.
