Hello,

So, we have now thoroughly checked your Site again in this regard, the buttons including Personalize and Add to Cart are appearing on the Products: https://snipboard.io/8oU1hp.jpg

Whereas, the Layouts related issue is concerned right now all the Layouts on your Site are in Draft and not enabled. Further, when we checked one of the Single Product page of your Site > the Related Products section doesn’t have the Personalize button on the Products right now: https://snipboard.io/Ki6deO.jpg

Please check back your Site after completely clearing the browser and server cache.

Best Regards.
