There seems to be a bug in the UniController application with changing basic settings.
1) Load UniController
2) Under the "Apache" menu, select "edit basic and modules" and then choose "edit basic configuration"
3) Enter a valid email address under the "server admin email" that has a TLD with more than one dot, or a TLD that is only two characters.
firstname.lastname@example.org = works
email@example.com = works
firstname.lastname@example.org = works
email@example.com = doesn't work
firstname.lastname@example.org = doesn't work
email@example.com = doesn't work
firstname.lastname@example.org = doesn't work
The error given is "admin E-mail: E-mail invalid format".
