I have had a search in the forums but so far nothing directly relevant, so apologies if this is a repeated issue.
Basically, with my membership site (beta), I want to make the latest blog posts available to everyone, but then change the category/remove the "latest" category after a time so it's only available to members. However, while everything works fine for logged in members, for unlogged in users, the posts are being listed as "uncategorised" and the link is still pointing to "latest", so the post cannot be found. Disabling Membership Pro fixed the issue so it's clearly related.
I have permalinks set up in my favourite, simple way: /%category%/%postname%/.
Thanks in advance for your help.
