Just installed CB1 RC2 on Joomla 1.0.8.
If you look at the line 2769 of the code in admin.comprofiler.html.php you will see '<?' instead of '<?php'. My system has OPEN_SHORT_TAGS=Off so could not parse the <? short tag. Each page throws up a "unexptected $ens statement - cannot parse.....line 2769" message
I changed the script to <?php and hey presto, it works!
This would be a trip-up for other newbies like myself that have OPEN_SHORT_TAGS=OFF. The rest of the code uses <?php so this line shoudl as well, just on a tidiness principal.
Good product though!
