What can I do? I use iPage as provider for years now.
Maybe a solution is to go to www.vanderleevineyard.com, then open blog, etc?

When I open a link on any hackaday project page, firefox complains about security issues. Then I simply remove the https prefix, hit return again, and firefox is happy. May kaspersky is detecting something similar?

Are you sure? yes | no

kaspersky says most of the links are "bad"

Are you sure? yes | no

Hi Gary, I changed the links. My (new) Mac automatically added "https" when copy/pase links, have removed all the s-es.
Please let me know if it's OK now.

Are you sure? yes | no
