First, congrats and thanks for this plugin. It looks awesome and has just everything I need.
I'm stumbling on a problem though, and I think it's related to the domain mapping plugin (WordPress MU Domain Mapping 0.5.3) I use.
When someone (a logged in user or a visitor) tries to subscribe to the newsletter (via /newsletter or the widget), the ajax wheel turns and never stops.
When I look at what happens, I first see a POST to http://www.partance.org/wp-admin/admin-ajax.php with the following POST data :
The server replies with a 302 to http://partance.blogs.lstilde.org/wp-admin/admin-ajax.php (which is a normal behaviour with WPMU Domain Mapping).
Then, there is the second request firing to the new location but now it's a GET, and there is no GET variables passed.
May be redirects (caused by the domain mapping plugin) are handled erroneously somewhere in the code, and prevents registration from working properly ? The rest is working fine (including unsubscribing !).
What do you think ?
Thanks for reading,
