Security error msg. Only on main page

[RexNL]

Hello all,

I have a problem on which I desperately need some advise.
With the little webdesign knowledge that we have here, we 'inherited' a website that belongs to our company.

There is one problem which I really don't know how to fix and have spend several hours browsing the net to find a solution. To no avail.
Whenever customers visit this website (www.myrexnord.info) (IE, firefox tends to just continue loading), right at the very first page they get the following security warning:
"Do you want to view only the webpage content that was delivered securely?"
"This webpage contains content that will not be delivered using a secure HTTPS connection, which could compromise the security of the entire webpage."

This obviously is a problem, as we do not want to change IE8 security settings with ALL of our customers.
It appears to be specifically the main page that comes up with this security warning.
I have had contact with our Provider who delivered our SSL certificate. They confirmed the certificate is installed correctly. So it should not have something to do with that.
He mentioned something about web scripts/scripting?

I have no idea how or where to fix this, it would be much appreciated if someone could help me out. I have access to Typo 3, Plesk control panel and FTP.

Thanks in advance,
Paul.

Problem solved.

The following solved the problem.

The main page had the some references at codebase to webaddresses, apparently the embedded flash movie:


'codebase','https://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,0,0','width','267','height','200','id','FLVPlayer','src','FLVPlayer_Progress ive','flashvars','&MM_ComponentVersion=1&skinName=Clear_Skin_1&streamName=images/rexnordMovie&autoPlay=true&autoRewind=false','quality','high','scale','noscale','name','FLVPlayer','salign','lt','pluginspage', 'http://www.adobe.com/shockwave/download/download.cgi?P1_Prod_Version=ShockwaveFlash','movie','FLVPlayer_Progressive' ); //end AC code
</script><noscript><object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="https://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,0,0"

These addresses were previously HTTP: addresses instead of HTTPS:
Edited them to be HTTPS: and problem was solved.
