Looks like your PHP server has shorttags off. The EXIFER library associated with Plogger 2.1 uses shorttags to start PHP blocks. Instead of being parsed and executed, it is being spit out plaintext.
If you do a search and replace on the EXIFER (all PHP files in the EXIFER folder) files everything should work. Replace "<? " with "<?php " globally and reupload the files.
