I’ve installed this plugin and it appeared to be just fine. It looks great, but when I try to use it I get strange errors.
This error pops up after signing in with my login and password.
Can’t load entry #.
This error pops up after clicking, “Click here to install the Comment Registration templates for this blog.”
You tried to set inexistent column origname to value Commenter Registration on MT::Template at /usr/home/joschino/publichtml/cgi-bin/managed-mt/plugins/CommentRegistration/CommentRegistration.pl line 187
I’m using 4.2 http://www.prgm2.com Any ideas?
The other problem is, I can’t figure out how to restore the default! Please help!
Movable Type Pro version 4.21-en with: Community Pack 1.6, Professional Pack 1.2
Thanks, Josh

Just remove the plugin and you should be good to go. If any modifications happened to your main sign-in templates, you should be able to fix that by refreshing the contents of the tmpl directory under the main MT directory. Usual caveat: backup first.
