Hey Tsvetelin
This was the intended behaviour of the shortcode but now I think about it, its pretty clear that some users may not wish to see unfiltered results right away!
I’ll get this added as optional over the weekend.
RE The other way, the XHR response is because it is doing a cross domain request.
This plugin, uses built in WP functions for finding out the right URL to go to, the only thing I can think of is that it may be trying to access a different domain because of some of your settings?
This can be because S&F is trying to access a “https” version of the site, when it is in “http” (or visa versa) or that it is trying to access a sub domain.
A link would be useful so I can take a look.
Thanks
