PEAR static method call warning
PEAR static method call warning

Forum https://forum.pfsense.org/index.php?topic=86478.0
PEAR is used by
IPv6.inc
auth.inc
captiveportal.inc
radius.inc
xmlrpc_client.inc
radius_accounting.inc
radius_authentication.inc

I have just changed this 1 function to "public static"

Also used are:
PEAR::raiseError
PEAR::loadExtension (already has "static function")

Not sure if PEAR::raiseError will throw a similar "static method" call
warning, not game to touch it.
