I am using Chrome on a PC running Win 8.1 with two admin accts and one child's acct. Both admin accts can use Chrome without a problem but if my son tries to access a web site through Chrome he gets " SSL protocol error". I noticed that when I look at certificates within Chrome on his account the certification path says "This certificate has an invalid digital signature". This problem only started two days ago. He can use IE with no problem, as can both admin accts.
Do I just have to update certificates in Chrome? If so how?
