I am using WP 2.3 and adding my own tags into the new tagging field. However, I want to change all tags to lower case. Everytime I go into an individual post and change "Berkeley" to "berkeley," it just goes right back to being "Berkeley." It doesn't save the changes.
I've gone as far as to remove "Berkeley" from all posts tagged as such and then start retagging as "berkeley," but it's as if it remembers the former capital case.
Is there a file I can cleanse of the wrong tags? Or delete all tags and start over? The Tag Cloud widget came with my wordpress (or theme: Mandigo) and I can't find any place to make edits to it. It's infuriating to keep editing the tags and have the edits somehow not take.
My website is http://www.eastbayinsomniac.com and the tag cloud is in the upper righthand corner.
