Why doesn’t the “Add to cart” button work?

[ashuhhlay_tacky]

I’ve noticed that not one item in my store can be added to my cart since the “Add to Cart” button isn’t able to to be clicked on/loaded properly. When I try to see my cart and click the shopping cart icon, all I get is a red error message. 

I’m also not sure why I can’t see the various images of a single item when I click on an item to see the specifics. I’ve tried to upload another image to an item to test if it will load properly then, but still nothing. I’ve also tried different web browsers and devices to test— but the results are all the same, unfortunately.

I know my site was working properly a few weeks ago as I made sales and completed shipments— this is very random and I’m not sure how to fix this. 

I did notice that the icon that typically showed on the upper right when I’d edit my site, reading, “Now accepting orders” was missing. I tried exploring more into my settings to see if it had something to do with this. but I couldn’t find anything to toggle this sort of thing.

Could anyone help? I appreciate it greatly!
