I'm having an issue with a third party plugin called WP-Calendar, where clicking on the "next" and "prev" links in a small calendar results in a redirect error.
This problem only appears to be happening on archive pages, as I have the calendar on the front page of a few MU pages and it does not have the same problem.
Clicking the links basically adds the following to the URL:
Which changes depending on the current month viewed. This leads me to believe that there's something up with the archive / category page accepting parameters through $_GET. To test this theory I tried ?a=b at the end, and I still got the same redirect error (The page isn't redirecting properly).
Anyone know why the archive pages won't accept inputs through the URL?
EDIT: Some additional information that I should've mentioned, I've tested all of the plugins and the problem still exists after disabling them. The theme being used is a style modified version of this: http://www.woothemes.com/2008/02/gazette/. Also the permalink settings are custom to: /%category%/%postname% and category base is . to get an URL such as myurl.com/category to work for a category landing page.
