znc webadmin module V 7.4 and 7.5

Hello

i was using znc on OpenBSD 7.4 and it worked correctly, then i did a clean
installation of 7.5 and znc does not create the webadmin page, irssi said
that webadmin module is loaded! Then i went back to 7.4 and it has the
exact same behaviour. Tested adding LoadModule webadmin at znc.conf and it
failed.

i went to znc irc channel and they said that it could be the OpenBSD package.

Could somebody help please?

Thanks misc
