I'm new on shopify.
I've tried to find similar questions but I was not successful, so please excuse me if it's something obvious.
I've created a shop for a client and installed a theme bought on Envato. This is my client website still in progress: https://dagojewels.myshopify.com/
Then, as I did on any website I built in the last 20 years, I started to "hack" css. In this case I created a custom css theme in the assets folder, as suggested on the shopify official docs.
Everything was fine, and I was working, until, at one point, trying to enter again in the editor with the "Customize" button, on the Themes page instead of opening the theme editor as usual, a page with this message appeared:
The Theme you're looking for couldn't be found
Just below it, a button with "go to themes" where my custom, unreachable theme is on top and clearly in the list!
What happened?? How can I recover the work I did??
I DIDN'T touch anything in the theme files apart for the custom css file
Just before the problem appeared, I was loading images for the main slider, nothing else.
Can someone help me?
Thanks for your time!
