Hi,
I think that you'll maybe find some solutions
there
:
I would say that this comes from the fact that you have the register globals option of your php turned on, which you shouldn't. Because of that, the option variable we use in our view overwrites the option variable that joomla uses on it end and thus you can that error.
Three solutions:
1. you change that line by:
$option = preg_replace('/[^A-Z0-9_\.-]/i', '', JRequest::getString('option'));
2. You edit the file option of the view product via the menu Display->Views and you change the variable $option by $optionElement to avoid the conflict.
3. You deactivate that php option, supposing that you have access to your php.ini
Hope this will help you.
