Doesn't work with microsites module.
In the subscriber, the destination when using a microsite includes the protocol and domain for example http://bla.com/my/page. This fails in the matching and doesn't redirect as the path stored in db is relative.
Patch included to extract just the path.
Not all content is available!
It's likely this issue predates Contrib.social: some issue and comment data are missing.
Thanks for the patch! I can confirm that the same issue appears for a Domain Access module, strange that no one reported it before. The patch solves the problem.
I ran into this with Domain Access as well. Patch works great!
