Error in class.frontend.php

[mr-fan]

Line 1208 there is a typo witch case problems with the var $month.link_next_month

on line 1208 is:
'link_next_month' => sprintf('%s?%s=%s&%s=%s&%s=%s&%s=%s',

should be:
'link_next_month' => sprintf('%s?%s',

then the link for the next month works in the frontendtemplate correct!

best regards mr-fan
