Hi there. I am just building my store and will be ready to launch in a couple of weeks. Like everyone, I am trying out some apps. I was looking for a review app and wanted to start off with a free app, so I installed stamped.io however I did not realise that I couldn't get photos on the reviews, so I deleted the app and installed another (Photo Reviews and Testimonials)
My problem is now that I think I may have caused a problem by deleting the stamped.io app. I deleted it from my app list, but then it still showed up on the page, so I deleted the last line of the product.liquid file where it was located. Now I can't seem to install any review apps.
Could I have removed something vital from the product.liquid file? Is this usually how to remove an app?
