HTTPS breaking Stylesheet

Already spoke with DASP Support, who are great but this is dev issue.
Don't understand it, Style sheet link request is not being blocked, but a usercontrol stylesheet reference is being broken.
In http everything is fine. In https everything except for this is fine.

Note- SSL certificate is currently expired, but doubt it is the cause.

Thanks in advance.

 

Hi,

The UserControl, ascx, has it's own Stylesheet, and reference link. The cs file is hosted by the same URL space.
It works fine but not when the site is accessed over https.
Nothing else fails over https.

Thank you for helping

 

Hi,
Normally the Menu/Usercontrol looks fine




But after entering the site through https, the megamenu.css is not called, or the call never goes out. The GET does not appear.

 

Hi Frank,

Is there anyway to send the URL in a private message for this business.

I've used Firefox and Google Dev tool and find that no GET request is ever made to megamenu.css, which is how the menu is a raw html list.
I don't uderstand why the request is never sent.

 

To send a private message just click the recipient's picture/avatar, then click, "Start a Conversation."

 

Thanks for the help, It's working using relative path.
Originally I tried using ResolveURL and it wouldn't work for stylesheets.
Why won't absolute path work? Because it's a usercontrol?

 

Hi Frank,
I tried switching it to HTTPS absolute path.
