 * There’s a bug in your error handler that makes your error handler produce an 
   error whenever there is a bug in something unrelated to Timely. When I’m working
   on an unrelated plugin, I have to deactivate Timely in order to debug my plugin.
   Otherwise, I always get this error no matter what the bug actually is:
 * Fatal error: Uncaught TypeError: Argument 1 passed to Ai1ec_Exception_Handler::
   handle_exception() must be an instance of Exception, instance of ParseError given
   in /customers/f/5/4/yoursite.com/httpd.www/wordpress/wp-content/plugins/all-in-
   one-event-calendar/lib/exception/handler.php:191 Stack trace: #0 [internal function]:
   Ai1ec_Exception_Handler->handle_exception(Object(ParseError)) #1 {main} thrown
   in /customers/f/5/4/yoursite.com/httpd.www/wordpress/wp-content/plugins/all-in-
   one-event-calendar/lib/exception/handler.php on line 191
