I get an Internal Server Error when I do a rebuild on my Index pages.
All others (Indiv, Monthly, Cat) rebuild just fine.

Any tips?

I'm running 3.2 on my own plan @ DreamHost w/ the Code Monster plan

**update**

I'm getting the premature end of script headers error message in my server logs.
I know there's a topic on this but it doesn't say anything about MT 3.2

This Knowledge Base article has some things to check:

My bad, I should have mentioned that I checked permissions and paths to perl and the whole nine yards.

This problem suddenly appeared for no apparent reason. I hadn't changed any files or settings on the server, so I am mystified.

You may want to check with Dreamhost and see if they've upgraded anything recently in that case.

I did check and they said the only upgrade they performed that affected MT users was back in October, but my problem surfaced recently so that wasn't the cause.

Is there some kind of fix we can adapt from the problems with MT 2.x to work for 3.2?

Could you rebuild each of your individual Index templates to figure out which one is the troublemaker? What plugins do you have installed?
