All your template files have other file permissions (read/write - read - read, 644) than the other PHP theme files (read/write/execute - Read/execute - read/execute, 755). http://www.december.com/unix/ref/chmod.html
Normally 644 should be sufficient, but that may depend on other settings on the web server as well. Perhaps the template files have another owner (i.e.because you uploaded them with another FTP account than the default theme files)
I'd either give the template files a 755 file permission as well, or if their owner is different, change their owner to the owner of the other files. This would be done through the SSH (which on a virtual account you won't have) "chown" command, or by uploading them through the same FTP account the other theme files were uploaded with.
