extra ':' in URL after 'localhost'

[folkfreund]

I have a problem using helium in localhost installation.

• Startpage: http://localhost/vhosts/mypage/index.php/kalender.html
• Pagelist:
  index.php/kalender.html
  index.php/terminvorschlag.html
• Result:
  Error 404
  because extra ':' in URL after 'localhost'
  http://localhost:/vhosts/folkfreun.de/index.php/assets/css/4cc5c0fd7986.css

Any hint what I'm doing wrong? Or is this an error?

Can you try the page list as fully qualified urls and report back?

E.g:
http://localhost/vhosts/mypage/index.php/kalender.html
http://localhost/vhosts/mypage/index.php/terminvorschlag.html

Same as before.
This is a portion of the normal page source:
<base href="http://localhost/vhosts/mypage/">
<meta name="robots" content="index,follow">
<meta name="description" content="">
<meta name="keywords" content="">
<meta name="generator" content="Contao Open Source CMS">
<link rel="stylesheet" href="assets/css/4cc5c0fd7986.css">

When running helium, the browser correctly displays the configured pages but then reports the error.
The correct location of the CSS should be
http://localhost/vhosts/mypage/assets/css/4cc5c0fd7986.css
So: it is not only the additional ':'.
I also tried to put "RewriteBase vhosts/mypage/" in my .htaccess, but this didn't help either.

Ah, sorry for the typo in my first post. I wanted to replace 'folkfreun.de' by 'mypage'.

Hmm. I suspect its because you're using . Helium expects href's to be full or absolute.
