I try to use the following plugin to fetch subscribed articles:

from calibre.web.feeds.news import BasicNewsRecipe

class TyzdenRecipe(BasicNewsRecipe):
    title          = u'.tyzden'
    oldest_article = 7
    max_articles_per_feed = 100
    needs_subscription    = True
    language = 'sk'

    feeds          = [(u'.tyzden - clanky z tlacenych vydani', u'http://www.tyzden.sk/rss/clanky-z-tlacenych-vydani.xml')]

    LOGIN = 'http://www.tyzden.sk/prihlasenie.html'

    def get_browser(self):
        br = BasicNewsRecipe.get_browser()
        if self.username is not None and self.password is not None:
            br.open(self.LOGIN)
            br.select_form(nr=1)
            br['user'] = self.username
            br['pass'] = self.password
            br.submit()
        return br

It gets to the right form and finds the right fields but then crashes when trying to submit the form:

The last 30x error message was:

I don't understand why this is happening... Any idea?
I should mention that login works fine when I fill the form in a browser. I double checked that correct username and password are inputted in the scheduler also...
