I really like your plugin but I am having issues with multiple sidebars appearing on single posts/pages when only one sidebar should appear (the problem doesn't affect category archive pages). This problem is caused by the addition of tags to a post. I have found a fix but I think it would be better if you could make changes in your plugin. I will explain the problem and also my fix:
A page for a podcast on football has its own sidebar with single & archive exposure. The "football" category also has its own sidebar with "single & archive" exposure. (please note the podcast and football categories are each top level categories)
Everything works fine until I start adding tags to the individual posts: if I add "football" as a tag to a podcast post, then the "podcast" sidebar and the "football" sidebar get displayed. If I delete the tag "football", only the "podcast" sidebar is shown.
It seems that if the category slug (football) and the tag (football) are the same, the sidebar is shown.
How I fixed it:
I changed the slug of the category "football" to "football-football" and the problem was solved (please note, the category name was left as "Football"). The tag "football" could stay as it was. I then had to change each category slug so that they were not exactly the same as the tag (generally by adding "-football" after each one).
Everything works but it would still be great if you could add an option to deselect tags for awareness.
Thanks for a great plugin. You're a star!
