Due to a bug in Chrome, versions of Chrome 53 that are more than 10 weeks old now display this error message for all websites using Symantec certificates that were issued on or after June 1, 2016 (including from Symantec-owned brands like Thawte and GeoTrust). As of Friday, November 11, 2016, website visitors can simply restart Chrome to avoid the bug. Website operators can switch to a certificate from a different certificate authority. (SSLMate issues Comodo certificates, which are not affected.) The rest of this post still applies to new versions of Chrome.
