On a technical level, you're seeing DIR_WS_TEMPLATES mentioned in the error messages because the define() statement for that isn't being loaded properly.
And, since it's defined in your /includes/configure.php file, that points to you having problems in that file.

And, as Website Rob has pointed out, you have a number of syntax problems in your /includes/configure.php file. Start by sorting those out.

Also note that your admin side is controlled by a DIFFERENT file: /admin/includes/configure.php. While its contents are *similar* to the /includes/configure.php file, THEY ARE DIFFERENT, and not interchangeable. If you've mixed up the files, then things aren't going to work.
