Redirected to frontpage, not sub-page that's in the url (only on multi-site)

[Rvervuurt]

I've tried your plugin on a few domains and it works perfectly fine, but on a multisite installation, the plugin redirects to the frontpage after entering the code, even though the URL still has the redirect_to attribute.

On a single-page installation, the user is redirected as expected and the URL is "cleaned" afterwards, but on a multisite, it's just simply not redirecting to the page mentioned in the redirect_to-part of the URL.

Any tips on how to fix this?
