That's not good. Looking at the file it references, there's only one reason I can see this being a problem. Hope you don't mind making an edit to the file to check.
Open that file, and change the "<?" to "<?php" on the following lines:
line 84: <?
php } ###################### end login form #####################################
line 127:
<?
php
} # end logout
Sorry for the inconvenience. Let us know if this fixes your issue. Some servers and revisions of PHP are much more finnicky to having all code areas start with the <?php instead of just <? . Every once in a while, I forget to do it 'correct' <!-- s:? --><img src="{SMILIES_PATH}/icon_e_confused.gif" alt="
