My b2evolution Version: 2.x

I just discovered that the "Edit" button from the frontend (as I am logged in) doesn't work right. Pressing this button I get an error (Forbidden).

The "Edit" button from the dashboard (same blog post) works fine.

So I compared both links and now I can see that the link that is not working has something like this in the redirect part:

...&redirect_to=http://www.domain.com/weblog/blogs/index.php?blog3

This doesn't work. But changing it to

...&redirect_to=/weblog/blogs/index.php?blog3

just works fine. Is there any possibility to change the link so that it doesn't have the http:// anymore?
