Fixing scriptcase permission on your host
Some users have problems regarding permissions. When they are uploading files you can a message likes this "500 Internal Server Error" or when trying to creating the connection on scriptcase deploy environment you get an error like this "failed to open stream: Permission denied" or when you to try register in your scriptcase.
The first thing that some people say its to give 777 permission. The first "7" is the total permission for the owner, the second one is for the group and the third "7" is for everyone. Here is the trick, for hosts company, a permission 777 is a security issue for php files. "Everyone" can't have total permission. So you cant an internal server error.
The correct permissions are:
    Folders: 755
    Files: 644

2. Execute this command at the prompt for folders:
find /home/YOURUSER/public_html/ -type d -exec chmod 755 {} \;
3. Execute this command at the prompt for files:
find /home/YOURUSER/public_html/ -type f -exec chmod 644 {} \;

Execute this command at the prompt for fix owner (only if the files aren't if your username):
chown YOURUSER.YOURUSER /home/YOURUSER/public_html/ -R
