'You need to login' suddenly prevents users from reading articles

Help - anyone?

I don't understand the problem. Please send exact URL. Your description doesn't say anything, that's why I haven't replied.
If you can't post sensitive info here then contact me on mail.

Oh, I'm sorry - I'll try describe it better her, then

Site is www.bryllup.dk - what ever article you try to open, it says that you have to login, to read it. Even if you ARE logged in, you still get the same message.

Tak for instance this article: www.bryllup.dk/artikler-for-brudepar/k%e...e-eller-g%e6ld?.html

I noticed the problem after installing Fireboard BUT the reason why I post the question here, is that it works when I turn sefadvance off.

Was that a better descrition?

Please check your SEF Advance settings. URL replacements and Encode exceptions in particular. Remove them or revert to original settings and try again.

1. I uploaded latest 5.5 version inkl. htaccess file
2. I checked that the settings are the same as original
3. It doesn't work on content (allmost every article cannot open)
4. It does work for the rest of our site (like mtree and other links)
5. The same setup is perfectly working for our other sites - it's only a problem on www.bryllup.dk

Please help  :-\

Please use the .htaccess file that comes with SEF Advance and revert to original settings and try again.
If you can't find out what's wrong send a mail with the access info.
