Getting "Additional uncaught exception thrown while handling exception" I tried to install module Commerce Event Ticket, added all the requirements, then enabled Commerce Event Ticket and got an error message:

Additional uncaught exception thrown while handling exception.

Now, this message also appears on the page without admin rights i.e. my page is  Offline now! How can I fix this? 
Thank you!
Okay after this error, I ran www.mysite/update.php it applied a few updates after which I was able to access the admin pages but if i wanted to access my front page, I'd still get 

Fatal error: Call to undefined function field_info_field_map() in /home/content/q/u/a/quaa7882/html/sites/all/modules/addressfield/addressfield.tokens.inc on line 92 

instead. I then removed the module addressfield by ftp manually and my site was back up and running so that I can care about my module(s)  separately.
