[Users] Host Install Failing

Wed Dec 19 13:21:38 UTC 2012

Thanks Juan and Alon,

Juan: For some reason the url was wrong in my psql db, not sure if
perhaps the 3.0(early release) used the url in it's original form and
during the upgrade it wasn't modified.. just a guess though, it
certainly hasn't been modified manually before.

Thank you very much!

Regards.

Neil Wilson.
