It works now, thanks to LK, who helped me!
In ubb_lib.cgi I have changed
$vars_config{'MaxMemFields'} = 43; # maximum profile fields + 1. hard coded. That means it has to be changed here, Allen, not in vars_misc itself. <img src="https://www.ubbcentral.com/boards/images/graemlins/wink.gif" alt="" />
The 43 to 100
Thanks LK!!!
