Site certificate is invalid (expired root)

[VOWmaster]

Recently I noticed that when using Chrome or Safari my site -- www.virtualonlineweddings.com -- is coming up as "Not Secure", with message that my certificate is invalid (expired root). I don't get the same message with Firefox.

I disabled SSL and then re-enabled it but no effect. I also made sure no coding, headers/footers, etc. had no http instead of https, but there were only 2 which I changed and still no effect.

Can somebody please help with this?

@VOWmaster 

coming up with https here  on Chrome on a mac book

Thx for input whitemonkey. Strangely my experience is the opposite: I've found that with my windows laptop and chrome I'm not getting the security warning, only when using my (older) macbook with chrome (or safari) do I get the security warning. So maybe it's just an issue with my macbook.

@VOWmaster   are your browsers up to date?  clear cache, cookies etc

Thx, I clean my browser caches every day, and also checked that Macbook Chrome is up to date, but still getting the invalid certificate message.

@VOWmaster    weird   @Bernadette    any idea?

I also just checked Chrome on my Samsung Galaxy and didn't get the security warning, so again am thinking it might be some security issue with my older Macbook Pro (with El Capitan OS), as also getting the same message when using safari.
