Cannot login to frontend using multi domains (Joomla)

Hi there,

I am trying to login to the frontend of my site but the page just refreshes itself.

The default domain does not have any issue.

I am running Joomla 3.2.1 with virtual domains extension.

When I disable the USE-URL-rewriting, I can login without any issue. But then I will have /inde.php in my URLS :frowning:

Edit:I also have another extension on the same site - it is a forum extension called Kunena. I can login the sites using this extension’s login form.
Any help would be appreciated.

Thank you.
