Timeout may related to number of chacaracteristic?

Hello,

We got several white page on our host. So we copied the site on our localhost to work with it. Since, we see error description instead of white page like:

Fatal error: Maximum execution time of 30 seconds exceeded in C:\var\www\opticaldeals\components\com_hikashop\views\product\view.html.php on line 1156

When we assign 6 characteristics to product, everything seem fine. We start to get white page when we go to 8 characteristics.

Because my customer sell glasses. We need to go to twelve characteristics. Is hikashop support 12 characteristics?

Thanks,
Have a great day!
Sébastien
