 * I’m testing an application with the latest versions of WP,BP,bbpress and events
   manager plugin in a PHP 5.4 (FastCGI) environment. I tested this in a PHP 5.2
   environment and it didn’t give any messages. But when I move to PHP 5.4 it gives
   following list of messages.
 * I think this is a php versions compatible problem. If it is; then I would like
   to know your recommendation of use of the Events manager plugin with this situation.
   Because I can explain the real situation to our client and deactivate the plugin
   temporary. Or if this is not a long term work, we can wait until fixing this 
   from your end.

 * Is everything else is working aside from these messages? if yes, maybe you can
   try to turn-off display_error since it’s not a fatal error message?
