Rapidweaver 7.1.7 wrong Reference to CSS file

Hi There

I am running RapidWaver 7.1.7 to build the following site: https://www.andreas-horvath.ch. I have the following issue: When I go into the details of my blog, e.g. http://www.andreas-horvath.ch/Blog-2016/files/Blog_20161128.html the CSS is not found. In the html-source I find: <link rel=“stylesheet” type=“text/css” media=“all” href="…/https://www.andreas-horvath.ch/rw_common/themes/blog/consolidated-2.css?rwcache=501943000" which is obviously wrong (look at …/ suffix before https://.

Any ideas how this can be fixed?

Thank you in Advance,
