I received the following fall error when submitting the first event registration on a form I created. I have just updated to 4.6.10 on a new website. Any help will be most welcome.
Fatal error: Uncaught CRM_Core_Exception: [0: Transaction integrity error: Expected to find active frame thrown in /home/sites/rcsqsales.org.uk/public_html/fbabseil/sites/all/modules/civicrm/Civi/Core/Transaction/Manager.php on line 107
I have The full backtrace and will post, if required.
