I installed Bolt on my server - Windows XP - in a subdomain made for the purpose. But I found that it does not find the css-file for the standard theme. Then I changed line 12 in header.twig from:
<link rel="stylesheet" href="{{ paths.theme }}css/style.css"/>
to
<link rel="stylesheet" href="http://bolt.salldata.dk/theme/default/css/style.css"/>
that way it works? But it seems to be a more general problem, as several links are undefined. You will see it, if you go to bolt.salldata.dk and tries to click on one of the links in the page.
