Cannot make non static method static
I'm having an issue installing Gnu Social on my XAMPP server. On the installation page I get the error:
Page notice Initializing... Starting installation... Checking database... Creating database tables...
Fatal error: Cannot make non static method DB_DataObject::factory() static in class GS_DataObject in C:\xampp\htdocs\gnu-social-master\classes\GS_DataObject.php on line 234
I am running with PHP 5.6, but on a Bitnami server running PHP 5.5 the installation works without this error. It might be a PHP issue.
