I am having the same issue and tried all option above. any help appreciated. The issue only appears with IE9. all working fine with FF and Chrome. any idea where this is comming from?
did anyone made similar experience? I can not get the plugin work on an IDNA domain https://überwachungskamera.ch/ we had little to no challanges so far with WP on IDNA. issue: the plugin will try to add the redirection but it will not complete. we stopp it manually after about 5 minutes without success
