 * Hello, I’m using Events Manager in our site. I saw in the server logs that a 
   warning keeps appearing, stating that “strstr(): Empty needle” in “wp-content/
   plugins/events-manager/em-posts.php:273”.
 * Any ideas on why is this happening? Does this affect the server performance?
 * Thank you very much!

 * Hi,
 * Not getting this PHP warning, however, everything should still work except for
   PHP Fatar error notification. alternatively, you can disable wp_debug and then
   install WP plugin to monitor your WP error logs.
