How to restore deleted index code in liquid themes?

[Avni25]

 I accidentally deleted the index code from the liquid themes and now I cannot roll it back. Can someone please help.

Do you know what theme you are using? You may be able to reinstall a free theme from shopify, and copy the code for the index file over from the new one. If you're using a purchased theme, you may have to contact the theme developer.
