Thanks,Sorry the link was for the old version:http://mirror.contribs.org/smeserver/releases//10/smeupdates/x86_64/repoview/phpki.htmlreturns a 404 error here
I didn't enable smetest as the instructions said:
yum --enablerepo=smecontribs,epel install smeserver-phpki
once I enabled smetest smeserver-phpki-ng installs correctly
thanks for the help
Regards
Rob
