I was having the same problem as everyone else….upgraded to wp 3.0 and got a blank post.php screen whenever I tried to post an event. Normal posts went up fine but event posts would yield a white screen. After reading through the thread, I commented out what paulie suggested
if( is_string($_POST[$htmlElement]) ) $_POST[$htmlElement] = filter_var($_POST[$htmlElement], FILTER_SANITIZE_STRING);
in events-calendar-class.php using the plugin editor. Super easy and it worked! Thanks soo much. Didn’t even need to upgrade or downgrade.
