Hi @KumaranV ,
This is Theodore from PageFly - Shopify Page Builder App.

You're experiencing problems locating the main-product.liquid file's thumbnail's class name. You can attempt to identify it by:
- Using the developer tools in the browser to inspect the element on the product page.
- I'm looking through your theme files for the product-thumbnail.liquid snippet.
- looking for terms like "image," "thumbnail," or "product__media" in the main-product.liquid file.
- Searching through all theme files with the Theme Kit software.

I’ll be so happy if my suggestion can help to solve your problem. If you have any further questions, please feel free to tell me.
Best regards,
Theodore | PageFly
