I have a tool link building block installed on Blackboard 9.1 SP14. When the user click on the tool link, the user is somehow redirected to the Blackboard's homepage with a mixed content warning. Selecting "See all Content" doesn't help as user had been redirected away from the building block.
Further investigation indicates that this issue only happens on IE. Chrome is working perfectly. The part that puzzled me is why the tool link was redirected to the Blackboard's homepage with a mixed content prompt. There is no error from the log regarding this issue.
Anybody encountered this issue before?
