I am running into issue while using worflow in the site over HTTPS. When Item is either approved or rejected basically page refreshes and in the console i get error like
Mixed Content: The page at 'https://site/sitecore/shell/default.aspx?sc_lang=en' was loaded over HTTPS, but requested an insecure resource 'http://site//sitecore/shell/default.aspx?xmlcontrol=Workbox&mo=preview&reload=1&{190B1C84-F1BE-47ED-AA41-F42193D9C8FC}=0&{46DA5376-10DC-4B66-B464-AFDAA29DE84F}=0&{FCA998C5-0CC3-4F91-94D8-0A4E6CAECE88}=0'. This request has been blocked; the content must be served over HTTPS.
By the way we are using Sitecore.NET 8.1 (rev. 160519)
I found same issue at with no answers.
