Would you be able to confirm what theme you are using for your store and if you could remove/ uninstall any apps which you aren't using and then try again and see if that helps fix it for you?
If removing the apps doesn't make any difference, your best bet would be to reach out to the theme developer who developed the theme or if it is a free Shopify developed theme it might be something which our theme support team can look into.
I have an issue win my store. In every blog and page html edit part I see this code:
I am using free Brooklyn theme. Can you please help me with this.
This is my store name: adroit-world-canada
Is this happening on your public store or in your admin? I took a look at your store and didn't see anything similar on the blog page anywhere. Let me know!
