I installed a module ajax add to cart and when click add to cart, it show error
Refused to execute script from 'http://.../ajaxcartsuper/ajaxcart/delete/id/...' because its MIME type ('text/html') is not executable, and strict MIME type checking is enabled.
I saw it in the head.phtml file
<meta http-equiv="Content-Type" content="<?php echo $this->getContentType() ?>" />
But i cann't fix it, please help me.
