I created a custom product detail template, but when I view a product page, it's blank!
If this happens to you, then it's likely that there is something in your code that the system doesn't like, namely PHP. With our new token system, PHP is no longer allowed. Look through your custom template and see if there's any PHP commented out - this is what you'll need to remove. If you're not able to resolve this, please submit a ticket and our support team will take a look at it for you.
