Jira Integration - Jira screen is not displayed on RQM

Hi

I have integrated Jira to RQM by OSCL CM adapter, no issues at this time.
When I try to attach a JIRA bug to a test case, the pop up window that should display JIRA bugs keeps loading and loading and the search screen is not displayed, I only get a blank pop up.

I got the same if I simply set mouse over the JIRA bug in RQM (for a already linked bug to a test case), no JIRA screen preview is displayed, however, If I click on the bug I'm redirected directly to JIRA with no problem.

I tried this process on Firefox, IE and Chorme.
For FIrefox and Chorme I got blank screen and for IE I got a pop up "Only secure content is displayed". If I click on "Show all Content" I get this error:

Error: com.ibm.team.repository.web.transport.ServiceResponseHandle(): invalid parameter types. Expected object (contextObject, successFunctionName, string errorFunctionName).

If I click OK for that error message, the RQM Test Case screen is displayed but broken, missing some links and displaying not working links and also, I cannot see JIRA preview screen on RQM

Does anyone know how to fix that? Please Help
Regards!
