Hi there, @Sagiv!

While we're not able to provide support for custom coding from here in Shopify, there are a couple of options I'd like to share with you here.

You can try reverting changes made by rolling back to an earlier version of your theme files.

This would allow you to go back to a saved version of your previous .liquid files, but would not apply to changes to .css files. 

Should this not work to resolve the issue you reported here, it may be necessary to download a fresh copy of this theme from our theme store.

Could you let me know the name of this theme as you originally downloaded it?
