Cannot drop a file to Tempshare & invalid cert. warning Feb 16, 2021 By Yuphaphann Hoonchamlong I cannot drop a published zip file to tempshare "Drag your zip file here" box. I did not have this problem last year, FYI. Also, both Chrome & Firefox gave a warning of "invalid certificate". Firefox does not trust this site because it uses a certificate that is not valid for tempshare.articulate.com. The certificate is only valid for betaportal.articulate.com.
