I have a simple positive SSL for my primary domain on my multisite, but none of my subsites are covered. Some of my subsite users are getting messages that their website is "untrusted" when they type in their URL in the address bar (Firefox). I tested and found that Firefox defaults to https:// so of course if the user doesn't know better, they will go to the https:// version of their site and always get the error message.
My current host charges a lot for each additional ssl. Mine would be *.wordsandwriters.com
First question: is there any way to deal with this issue with the type of certificate I have and question two: where do you recommend getting a third-part affordable certificate that would cover unlimited number of subsites?
