Error Message - Live Code site

I am getting this error all morning when trying to access the sandbox on my live site.

Hi, can you share a link to the site so we can take a look? Does the live database work?

Note that we had some issues a few hours ago and they are resolved, I want to make sure it works for you as well or you have a different issue.

The live database is fine, but the sandbox is still down.
website is guardarena.com

Hello Anthony,
Could you try to hard-reload the editor (in order to clear your browser cache) and see whether the issue persists?

See this link on how to perform hard reload:

Hi Guy,

The hard-reload is completed, but the issue is still happening.

I tried loading your site and the collections worked fine.
Can you share a screenshot of the browser console? If possible, also the network tab:

  1. Open the browser developer tools, switch to the network tab
  2. Clear the network list before you open a collection (using the clear button, second from left in Chrome)
  3. Open a collection
  4. Take a screenshot (failed requests should be marked in red text)

Never mind Anthony, we now see the issue on our side. We’re checking.

Anthony, could you please send us a screenshot of a specific network request?
Same instructions as before - clear the network list and then switch to a collection.
After that, please select the request with the name [collection].json → for example “Guards.json”
Now we need 2 screenshots:

  1. A screenshot of the right section tab “Headers”
  2. A screenshot of the right section tab “Response”

I attached sample screenshots of a collection I have to show what I mean:

Hi Tomer,

I’m unsure of what you’re requesting.

I can’t seem to find those settings in dev tools

it seems to work now!

Great!
The problem you were experiencing looks exactly like a problem we had a few hours ago.
You may had some cache issues that prevented it from going away on your computer.
I’m still monitoring, let me know if it happens again.
Thanks for the patience and sorry for the inconvenience.

Hi Tomer & Guy,

Thanks a lot for your great help regarding this matter!
