Hi,
I´ve updatet to php5.4 and at my WP multisite I get html 500 errors when trying to reach my sites. Apache error log says: PHP Fatal error: Call-time pass-by-reference has been removed in /httpdocs/wp-content/plugins/nextgen-facebook/nextgen-facebook.php on line 298
On single WP installation all seems fine. What can I do?
best,
ben
