problem with MarvikShop on Jommla 2,5.8

I am using PHP Version 5.3.17 and Joomla! 2.5.8 Stable [ Ember ] 8-November-2012 14:00 GMT

Can anyone tell me what is going wrong please, I keep getting this displaying on the front end and on config screens on the backend, don\'t know how to fix it?

Any extremely simple instructions on how to fix this would be very welcome.

Thanks.

Paul

It\'s quite easy to solve. It has got to do with PHP 5.3.17

open the file and change these lines 393-400 into:

==============
if ($action_par != \\\'\\\') {
$action_params = array();
$action_params = explode(\\\'&\\\',$action_par);
foreach ($action_params AS $this_par) {
list($key, $value) = explode(\\\'\\',$this_par);
$form .= tep_draw_hidden_field( $key, $value );
};
}

===============
The split functions changed into explode
