Movable Type - Submit comment, returns blank screen

[Xtreme $niper]

I discovered today that my website was not accepting comments, and was returning a 500 Internal Server Error window. I did some looking around and found that somehow my mt-comments.cgi was not given any permissions (000) and so I fixed that and now the comments theoretically work. If someone tries to comment, the browser will show a white screen. The user won't know it, but the comment DID go through. Something is wrong. I've been doing some research online and I have found various people with the same issue, but nobody had a solution except one guy who said that he had some javascript that was interfering with the mt-comments.cgi. Unfortunately I don't think I have any javascript (and certainly have not changed any) other than sitemeter and google analytics.

Anyways, is anyone else out there with a Movable Type installation that has this problem? Thanks.

Blank screens when executing my MT CGI scripts (mt-comments, mt.cgi or others) generally means they have crashed. This could be due to a bad script or even problems with your webhost.

For example, if you have been getting lots of comment spam (especially if you have v2.x), webhosts sometimes will disable or block your script (with chmod 000 for example).

You may want to talk to your hosting company, and also use MovableType's trouble ticket system.

I used to get a fair bit of comment spam but my filter would resolve that anyways. I turned off my comment system after a while since nobody but spammers were commenting but then brought it back online a few months ago. I suppose it's possible that they did chmod 000 on my mt-comments.cgi, but I don't see why it would have been necessary. I'll submit a ticket to my host when their ticket service is back online (ironic, I know).

The "Comment Pending Message" template in the systems tab of the templates section is the page that should appear. I can't imagine what would be crashing. Maybe another script does not have sufficient permissions as well?
