[TYPO3] Error in submitting comments in TIMTAB/ve_guestbook

[Jesper Kristensen]

Hey

I'm newbee in typo3, but i've managed to configure a blog on my  
website using TIMTAB ver. 0.5.9., ve_guestbook 1.12, tt_news 2.4

Everything works fine, except adding comments to a blog. Submitting  
the comment form results in the same page is displayed in the  
browser, with my name, mail etc. in the form. Hitting F5 doesn't  
help. It will not add a comment...

My template configuration:

Constants:
page.file {

   template_main = fileadmin/kubrick/kubrick_main.tmpl
   template_std = fileadmin/kubrick/kubrick_std.tmpl
   template_single = fileadmin/kubrick/kubrick_single.tmpl

   css = fileadmin/kubrick/style.css

   template_tt_news = fileadmin/kubrick/kubrick_tt_news.tmpl
   template_ve_guestbook = fileadmin/kubrick/kubrick_ve_guestbook.tmpl

   #kubrickbgcolor = EXT:timtab/res/kubrick/images/kubrickbgcolor.jpg
   #kubrickbgwide = EXT:timtab/res/kubrick/images/kubrickbgwide.jpg
   #kubrickheader = EXT:timtab/res/kubrick/images/kubrickheader.jpg
   #kubrickfooter = EXT:timtab/res/kubrick/images/kubrickfooter.jpg
}
plugin.tx_timtab.title = Ida og Jesper i Toronto
plugin.tx_timtab_pi2.pidStorePosts = 50
plugin.tx_timtab_pi2.pidStoreComments = 104
plugin.tx_timtab.tagline = Historier fra Toronto
plugin.tx_timtab.homepage = http://www.idaogjesper.dk
plugin.tx_timtab.blogPid = 97
plugin.tx_timtab.homePid = 30
plugin.tx_timtab_pi2.enableBlogger = 1
plugin.tx_timtab_pi2.enableMetaWeblog = 1

plugin.tt_news.pid_list = 50
plugin.tt_news.backPid = 30

Setup:
  plugin.tx_veguestbook_pi1 {

   templateFile = {$page.file.template_ve_guestbook}
   limit = 1000

   _LOCAL_LANG.default {
     form_firstname = Navn
     form_submit = Tilføj kommentar
     form_email = E-Mail
     form_homepage = Hjemmeside
   }

   _CSS_DEFAULT_STYLE =
}

There is sysfolder for comments and the guestbook list and form are  
configured as required in the timtab manual..

I've looked high and low, with no look.. Can anyone help?
