This is an odd one ... When I attempt to save a new entry, I get the apache error page saying I don't have permission to run scgi-bin/mt/mt.cgi

Everything else works so I can run mt.cgi.

By trial and error, I found that if the entry contains a line break, I get the error message. If I instead use

in the post, it saves okay.

This is the first post I've made to the weblog in about 6 weeks. In the meantime, my ISP has switched hosts so I don't know if they've done anything that might affect this.

This is MT 2.661 on Linux.
