This one looks easy, not for me, though.
I modified a plugin for my client needs, and it works fine in the sandbox wp installation I worked it on, but when installing it in other blogs, randomly it breaks in different ways.
All of them related to one of all the admin pages not containing
in the name.
1) I found that piece of info in the DB under transient-slug something.
Is that making the plugin to work in the sandbox website?
I haven't found any info regarding transient slugs.
2) Then, what piece of WP script is in charge of usign/or not that missing part of the URL?
One tip: If I add the missing part of the URL that makes it work in the sandbox installation, it says "I don't have sufficient permissions". Different message to what says if I type a non-existing url.
Oh, I forgot: One of the sites just takes me to the blog page (not home).
All of them latest WP versions, default pretty permalinks .htaccess code.
