Result: 403 error
Web Host: HostGator
To the best of my troubleshooting thus far, it appears that due to the fact that redirect_to parameter has "http:disappointed:" (or some combination) HostGator/mod_security blocks this request thinking it's a potential threat.
Is this something you can confirm is an issue on your end as well? Is there a potential workaround, perhaps at a code level?
