 * My host has moved my WordPress installations from a server with PHP 5.2 to a 
   server with PHP 5.3. I have 11 installations of WordPress and four of them do
   not work properly. I get the message:
    “Warning: Parameter 1 to ec3_filter_posts_fields()
   expected to be a reference, value given in …../public_html/stig/wordpress/wp-
   includes/plugin.php on line 220”

 * The error is caused by the plugin Event Calendar 3. I found the solution [here](http://wordpress.org/support/topic/php53-and-fastcgi-on-iis-with-wordpress?replies=6).
