adding the filter to site_url function seems not to work entirely for wp3.0.
in detail: if i add the filter, the action of loginform on rootinstance/LOGIN works, but on subinstance/LOGIN the filter doesnt affect the action parameter of the loginform, making the form useless.
here the produced tags:
rootinstance/LOGIN:
<form method=”post” action=”https://localhost/wordpress/login.php” id=”loginform” name=”loginform”>
subinstance/LOGIN:
<form method=”post” action=”https://localhost/wordpress/firstsubsite/wp-login.php” id=”loginform” name=”loginform”>
how should i add the filter?
