Getting Movable Type To Use 755

Claire's new entries in a new month would not display. Movable Type is storing entries in archive directories by month, and when creating a new directory in her blog, it was setting to 777. Since her banner uses php to randomly display photos, the JustHost.com server did not like running anything through the php parser in a wide open directory. It wants a minimum security of 755. I found an article that described adding the following to the mt.config file. Solved the problem.

HTMLPerms 0775
DBUmask 0022
HTMLUmask 0022
UploadUmask 0022
DirUmask 0022

The odd thing is other blogs were creating as 755 already, so not sure why Claire's behaved differently.
