Settings do not work

I am aware of the bug where setting aren’t getting applied. I will try to find some time soon to update the plugin.

Please be patient. It still works outside of “allowing post type ‘foo-bar'” to have featured image column.

The solution is to replace the function in line 194 in add_setting_post_types() function:

Replace:
array_merge(

With:
array_intersect(

This intersects the settings array (the ones you want) with the available post types and then you are left with just the overlap.

Thanks John.

When I find some time I will test this out.
