After update to 4.5.1 deleting cart doesn't work

Hi,

I've looked at the situation on both websites and I'm not sure what is the problem.
I can see the AJAX requests sent to the server to get the new cart module content and I can see the spinner added and then removed on the cart module on the pages.
So normally, the system is supposed to get the text returned by the server and replace the HTML content of the cart module with the new text and I don't see any reason why it wouldn't do it.
Of course, this works fine with the latest version on a local test website.

The only thing I noticed on your website, and which might be linked to the problem, is that when I look at was is returned by the server, I see that the server returns nothing at all:

On my end when I do something similar I get this:

So the fact that you don't have the text "The cart is empty" is normal as it can be removed with a translation override.
But the fact that you don't have the two HTML tags for the "loading" is strange.
I can only think it comes from your view override.
And with an empty response from the server, I can understand that the javascript thinks the cart module should not be updated.
And maybe it's linked to the update as we changed the javascript to handle the AJAX requests in between those versions.
However, you're saying that you still have the issue without the product / cart view override and I find this strange if my theory is correct.
So maybe I'm wrong and the issue is not linked to that.
It's hard to say without adding some debug to the javascript to understand why it's not updating nor being able to check your view override.
I would need a backend and a FTP access to look deeper into it and add some debugging. However, I would first recommend to double check that it's not linked to the product / cart override and to clear the cache of website and of your browser when you test this.

Hi,

I was able to access the backend and FTP you provided. However, I'm not able to modify the files via the FTP access. Could you please double check the permissions as I need to add debug in the files to better understand what's going on.

Hi,

Thanks, it worked.
I've changed the code:

text = '';
			}
		}
		if(text) {

text = false;
			}
		}
		if(text !== false) {
