you could put the following CSS into your <dokuwiki>/conf/userstyle.css (if it doesn't exist just create it):
div.dokuwiki div.sidebar_box a.urlextern { padding-left: 0; background: none; color: __wikilink1__; }
1. Yes this fixed the exact problem: Thank you!
2. Going back to the original question: How to do backlinks w/o using the website name such as:
[[/tag:biz_101?do=showtag&tag=biz_101|Biz 101]]
instead of:
[[http://foto-biz.com/doku.php/tag:biz_101?do=showtag&tag=biz_101|Biz 101]]
But that does not work. I have also tried putting doku.php in front w/o success.
