Okay that eliminated some of them but not all
There is only on thepage now and I can not find anything else to fix that was indicated in your link. They all refer to line 5 of registration.php and there is nothing that I can see wrong with line 5.
Here is the one error:
Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/content/b/r/i/bristolmgmt/html/vendorpage/pvregistration_Registration.php:5) in /home/content/b/r/i/bristolmgmt/html/vendorpage/pvregistration_Registration.php on line 225
Here are the rrors from after registration:
