internal server errors plaguing etherwork blog

I have no idea why the etherwork blog (my real blog) is suddenly plagued with internal server errors. For the most part, it seems to be only affecting the sidebar display (ie: sidebar is NOT displaying correctly) but it also seems to cause the page to not display at all if there is an attempt at commenting - there is a redirect to the internal server error page. This is quite trying, to say the least.

I have asked my webhost and it looks like it has something to do with my Wordpress installation. Because I'm using the "legacy" branch of wordpress, alas, it's up to me to fix the problem. My webhost cannot be troubleshooting their or my errors. RATS!

I'm not quite certain what I'm going to do about it: whether I'll upgrade to the latest wordpress or whether I'll switch to a different blogging platform like "live journal" or "movable type". Whatever I do, it's going to take time.

Rrrrrr. I loathe change!
