Hello, this is Peter from nabble support. A user has complained that he cannot register on this forum as the newly implemented "reCapture" threw and exception. this is due to the fact that the DNS issue where "http://itus.accessinnov.com/" is not pointing correctly to nabble server. How it worked in the first place I do not know. I have reset the domain name back to the original nabble domain name and now people can actually register on it.
To the owner of the site, if you want to do the custom domain please resolve your DNS issue!
