Is your WordPress sidebar gone? Or has it moved to a different location? This annoying problem can seemingly appear out of nowhere. One day your blog looks fine, and then suddenly your sidebar is all messed up.
This has occurred several times on my blog, and every single time it was due to improper HTML coding. Fortunately, it’s pretty easy to troubleshoot without being a coding guru.

Occasionally, sidebar problems need a more complicated fix and require some knowledge of CSS (Cascading Style Sheets). But fortunately, I’ve been able to fix the glitch every time just by finding and correcting basic HTML errors.
