Thank you very much! It seems my misfortune was only due to a small mistake. I hadn't included the subfolder in the error-handler:
$HTTP["url"] =~ "^/forum/" {
server.error-handler-404 = "/rewrite.php"

Re: [1.3] URL rewrite rule: lighttpd? (10 replies, posted in PunBB 1.2 discussion)
I have been trying to get rewrite to work with lighttpd and PunBB 1.3, but haven't been successful. Can one of you that has got it working please share of your wisdom?
For WordPress I'm using mod_magnet and a lua script, but that didn't seem to work with PunBB.

Re: [solved] Problems with translations in search.php (2 replies, posted in PunBB 1.3 troubleshooting)
Ah. I was so very certain that I had encoded all the files as UTF-8, but somehow search.php was saved as ISO-8859-1. A simple iconv took care of that problem. Thank you!

Topic: [solved] Problems with translations in search.php (2 replies, posted in PunBB 1.3 troubleshooting)
Since there wasn't any Norwegian translations for 1.3 available yet I've been doing the work my self. Everything work fine, except for search.php:
In Norwegian I need to use special characters such as Æ, Ø, Å. This works fine with the other translation files, but in search.php the main part of search.php went blank (except from header and footer) when using such characters. I then tried to change the translation of that file into html-entities which actually worked apart from the title of the search results page.
On that particular page the main content goes blank when using special characters in the 'Search results' field, also if I use html-entities these are displayed just as I wrote them: instead of 'Søkeresultat' it says 'Søkeresultat' in the page title and the breadcrumbs.
Any ideas how to fix this?
