Website Problems

A few readers have recently informed me that they are encountering the following message when they attempt to access this blog: 

Your connection is not private

Attackers might be trying to steal your information from  www.francisberger.com  (for example, passwords, messages, or credit cards). Learn more
NET::ERR_CERT_COMMON_NAME_INVALID

I experienced this as well on Sunday, but have since had no trouble getting to the site. I have been trying to figure out what the problem may be, but have not succeeded in discovering the root cause. I highly doubt hacking is involved. I mean, you would have to be an awfully bored hacker to waste your time messing around with this meager blog. In any event, I will keep investigating the issue until I figure out what the actual problem is, but that could take a while as I am not the most tech savvy individual on the internet. 

Any insights, suggestions, or advice concerning the error code above are welcome and would be much appreciated!
