Hi @basam , This is Theodore from PageFly - Shopify Page Builder App. For solving the problem about the Meta Field Tab Error, let’s try this solution:
To structure the 'Metafield Tab' on your Kala Shopify theme without coding skills, start by deciding what additional product information you want to display. Then, from your Shopify admin, navigate to Settings > Metafields > Products, and create your metafields by clicking on 'Add definition'. You won’t need to code; just fill in the details. If you’re unsure about editing your theme to show these metafields, consider reaching out to Kala theme support, hiring a Shopify Expert, or using an app from the Shopify App Store that can handle metafields. Always remember to backup your theme before making any changes. 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
