UBB.threads PHP Forum Software Community Forums UBB.threads 7 Version 7 Support Fatal Error when checking user

UPDATE - Yes, indeed installing iconv got rid of the error, but now I have a related question.

When I click on Check This User, the spam checker never shows anything for Email Status or Reg. IP status. Seems I got some indications before I changed servers. Any idea what else might be needed to make this function properly?
