In an attempt to update my theme, I’ve deleted all the personalization I had done to this blog. Oddly, it now appears that WordPress changed some things, and I can no longer customize my sidebars. I’m not very happy about that. Not happy at all.
Addendum:
I figured out what I did wrong. I’m still annoyed because I want to change the look of this blog and I’m having difficulty with the code. I need a decent FTP client.
