Ted here from Shopify, thanks for reaching out to us!
What is the name of the theme you are using? Can you remember the name of the file you edited within the theme? Before making any more changes, I'd recommend making sure to backup/duplicate your theme as shown in this guide, just in case something goes wrong when editing the code. If you can remember the theme file you edited, you can select an older version of the file; which would revert the code back to when you previously made the change. Here's an example of where you can select that option.
On saying that, if you are using a Shopify made theme I can certainly have our Theme Support take a look. I'm happy to pop an email your way or if you would like to contact us here directly we're happy to help!
Thanks a mill,
For that you can check in this file:
1. Template->collection.liquid OR
2. Section->collection-template.liquid OR
If you want to un-hide your price and title on collection page then for debut theme its most of in this file code.
If you have remove code then you have to do code for that. send em your store url.
As i can see in store you have title but cant show because of some css affecting or you have given.
1. Open Snippet->product-grid.liquid -> find "visually-hidden" from product title and adjust or remove it.
May be price not loading so you have to check in given grid file whats going on.
