If you are using the blog software called Movable Type and are receiving strange permission errors (resetting back to 666 and consequently receiving an internal server error), you will need to edit your mt.cfg (or mt-config.cgi) file.
Find the following lines:
# DBUmask 0022
# HTMLUmask 0022
# UploadUmask 0022
# DirUmask 0022
You need to remove the # symbols in front of all four lines, like this:
DBUmask 0022
HTMLUmask 0022
UploadUmask 0022
DirUmask 0022
If, and only if, your files are using .php extensions, you will need to also find the following:
# HTMLPerms 0777
# UploadPerms 0777
Uncomment those two lines and change it to this:
HTMLPerms 0644
UploadPerms 0644
Save and re-upload mt.cfg, and rebuild your entire weblog.
You have to do this because our server runs under SuExec. Uncommenting those lines will eliminate the permissions problems.
Save and re-upload your mt.cfg file to the appropriate directory in ASCII mode.
If you have done all of this and it still is giving you a forbidden error when viewing entries-- are you using categories? If so, you will have to change the permissions on the category folders manually, because Movable Type doesn't seem to do it on its own.
Say your blog is installed in a subdirectory called /weblog
Make sure /weblog itself is set to 755. Also make sure any folders underneath (your category folders) are also set to 755. Then rebuild once more, and that should do the trick!
If you do not feel comfortable editing the file, please submit a support ticket with your request that includes your FTP password and the directory where your MT files are installed and I will edit it for you.
