Minicalendar - "next"/"prev" don't work

HI,
I've got a problem with minicalendar module.

On sites where it's published as a module, like here:
joomla.kebeth-studio.com.pl/joomla25/
arrows "prev"/"next" don't work (for month and year).

On sites where is big callendar (as a component). like here:
joomla.kebeth-studio.com.pl/joomla25/ind...?month=02&Itemid=435
everything works fine, but only if I click arrrows in big callendar. When I click arrows on small one, TAGs disapear: <span class="sunday"></span>, <span class="saturday"></span>

(red color disapears)

regards, and looking for your help,
Adam

Hi Adam

It seems something doesn't work here. Could you please submit a support ticket sending us admin and FTP account of your site ? I will check to see what's wrong and get it corrected for you.

unfortunately, It's our local server and we don;t have FTP access from outside. I will try to make that on other server/ftp - so that you will be able to access and fix it.
It's a pure installation of your component so the problem is not a matter of my interference.
