I am using Chrome version 53 and none of the Filestack services seem to be working. Why is that?

Chrome 53 has a well known security Certificate Transparency handling bug which effected sites using certificates issued by Symantec, GeoTrust, and Thawte. Due to this bug, users may receive security errors in their browser console (for example "net::ERR_INSECURE_RESPONSE") when using Filestack's services. This will prevent Filestack from communicating with the browser. We suggest upgrading to a more recent version of Chrome where the bug has been fixed.
