Tab module error at https

Hello, we have switched our page on https. Now the Tab module does not work anymore. The module is still displayed, but they are no longer visible content. Where is the error?

Could you please provide me with a URL to your website, either here or via PM (click the “Private Message” text underneath my avatar) so that I may analyze it? It is a lot easier for us to diagnose issues when we have a live site to examine.
