Common Movable Type errors (with solutions)
Movable Type is a great CMS/Blog system built on Perl and version 4 was recently release for betatesting. However, the release candidate is not without bugs. Here are some problems and solutions I came up with:
500 Internal Server error on rebuild/Image upload (specially PNG).
Either you are running out of memory, or you'r Image::Magick installation is either broken or missing. If you visit http://www.yourdomain.com/cgi-bin/movabletype/mt-check.cgi and scroll down to "Image::Magick", does it appear as valid? Or does it say it's missing.
Either way (there have been reports that users with apparently OK installations is helped by this too) try using NetPBM instead. Follow this guide:

Using NetPBM with PNGs (... or File not found /path/to/mt/topnm"
Movable Types default NetPBM settings does not allow pngs (possible Movable Types default settings for Image::Magick either). Locate your Image.pm (In movabletype/MT folder), line 1XX (122 probably) and change:
my %Types = (jpg => 'jpeg', gif => 'gif');
To:
my %Types = (jpg => 'jpeg', gif => 'gif', png => 'png');
Otherwise you will get a "file not found: /users/home/etc/netpbm/topnm" error. Solution originally found on http://forums.sixapart.com/index.php?showtopic=54246
No entry ID on comments/commenting
Short answer: Make sure you have www in your CGIPath on mt-config.cfg (or remove it if you have).
Longer answer: This has to do with POST redirecting problems. Make sure your CGIPath in mt-config.cfg reflects your sites www-structure. If your adress is: http://www.domain.com/cgi-bin... You must include the www in CGIPath. But if your adress is http://domain.com/cgi-bin.. you must remove the www.
500 internal server error on commenting (... with NetPBM)
This could have several reasons. Start by turning off E-mail notifications (to make sure your sendmail isn't causing the trouble), then set "" to anyone. Also, see http://www.sixapart.com/movabletype/kb/comments/500_on_comment.html if their solution works.
If nothing else, you might have the same rather obscure error as me. NetPBM cannot produce CAPTCHA images, you will find this in your comment settings:
"No CAPTCHA provider is available in this system. Please check to see if Image::Magick is installed, and CaptchaImageSourceBase directive points to captcha-source directory under mt-static/images."
However, this does not stop MT from trying to initiate Captcha (even if it would later choose not to use it). Open lib/MT/App/Comments.pm and comment out (add # at the start of the line) in init(), from:
$app->init_captcha_providers();
to:
#$app->init_captcha_providers();
And your problem (might be solved), mine was.
