go to your_site/ws/plugins/content/joscomment.php
and delete this file and replace it with the one from the package.
Also this error means that you are using an old php version:
Parse error: syntax error, unexpected T_STRING, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or '}' in /hsphere/local/home/saudiboa/saudiemergencymedicine.com/ws/components/com_comment/joscomment/utils.php on line 40
Fix the other stuff first and contact your hosting to upgrade you to php5 (php5 was released 5 years ago, so they should support it)
