minifrontpage error "Invalid argument supplied for foreach()"

Dear sir,
Since the upgrade to joomla ver. 2.5.18 the minifrontpage modules doesn't work anymore.
in the page where the 2 minifrontpage modules should be there are only these errors:

I've tried to download and reinstall the module , but this doesn't fix the problem.
I've also tried to create an hidden menu voice ( blog type) and publish the category, but it doesn't work.

I don't think this issue could be related to hosting, because the module with the previous version of joomla works very well.

do you have any suggestion to help me to solve this problem?
Thank you very much.

please excuse me , I forgot to tell that this issue only shows when a user is logged in.
if I log out from my account the module works correctly.

ok , Iv'e applied the workaround for joomla 3.2 and now seems to work.
for those who have the same issue I will copy down the workaround from yur other post :

open the flie : modules/mod_minifrontpage/helper.php

at lines (115) find this code :

$model->setState('filter.date_filtering', 'relative');

change to

$model->setState('filter.date_filtering', 'off');

it worked for me.
thank you anyway.
