For now this fixes things indeed, however a warning from PHP.net:
“/This feature has been /DEPRECATED/ as of PHP 5.3.0 and /REMOVED/ as of PHP 6.0.0. Relying on this feature is highly discouraged./”
Putting “php_value magic_quotes_gpc 1” in my .htaccess file worked for me… for now.
Also added: “error_reporting( E_ALL & ~E_DEPRECATED );” to my bb-config.php
