I've watched the videos about creating an authentication provider and have created my own authentication provider. I've enabled it on the site and disabled the default DNN authentication. Having done that, the login doesn't appear in a popup window any more. I've inspected the source for the 'Member Login' link and it has changed since adding the additional authentication. How can I make it appear in a popup like before?
before:
<a class="hidden-xs udc-login" id="dnn_dnnLoginAH_loginLink" onclick="return dnnModal.show('http://xxx/Login?returnurl=/&popUp=true',/*showReturn*/true,300,650,true,'')" href="http://xxx/Login?returnurl=%2f" rel="nofollow">Member Login</a>
after:
<a class="hidden-xs udc-login" id="dnn_dnnLoginAH_loginLink" onclick="this.disabled=true;" href="http:/xxx/Login?returnurl=%2f" rel="nofollow">Member Login</a>
