Error after installing VM payment plugin

Hi,
After installing a VM payment plugin, I receive an error on the site, which seems to be related to image show GK4. I get the error "Notice: Undefined property: stdClass::$alt in /home/sites/site882/web/joomla3/modules/mod_image_show_gk4/styles/gk_shop_and_buy/view.php on line 76". Any suggestion what I can do to get rid of the error? The site is based on the InStyle quickstart, which included the module, but there doesn't seem to be a style for the template in the module.

Thanks,

Richard.

Hi

This is just a notification, not an error. You can simply lover error showing level to none in joomla gloabal configuration for server.
