I've been working on a simple app for a client written in PHP. I've used this the template https://github.com/nyalex/shopify-generating-api-token-guide for generating the access token and it worked fine on my development store, but on the actual client's store it seems impossible to install. When i try to, i just get a red circular forbidden sign between the client's icon and my app's icon on the install page and the install button is disabled with no error message.
What could be causing this and how can i fix it?
Thanks in advance!!
