I wake up this morning, and all of my links are messed up! I’m trying a back-up and upgrade of my WordPress software. Stay Tuned!
Update: I tried upgrading the WordPress software, which (maybe?) should have rebuilt all the links. It didn’t work. That’s all I can try for the moment–I might be down for a day or two. (I hope my entire database isn’t corrupted! I’m not sure how to fix that.)
Further Update: I remembered that there’s a “Permalinks” setting, where you can change what the URLs for you site will look like. So I played with that, and that forced all the urls to get fixed. Yay! I’m not sure how the problem started, but I’m glad it was an easy fix. (Especially since I didn’t have a recent backup of the blog!)
