All of the sudden I started getting:

```javascript
Access to XMLHttpRequest at 'https://www.wix.com/_api/wix-laboratory-server/laboratory/conductAllInScope?scope=wix-form-builder' from origin 'https://www.mydoamin.com has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

```

And it’s not limited to a specific site. I tested in 2 of my websites on different pages.  
Are you experiencing it too?

Thanks.  
I’m no longer experiencing it too.

Granted I’m reading between the lines, but I think he did. It probably went away with no action on his part after the relevant Wix developer or system admin noticed their mistake. I’ve run into CORS errors a couple of times myself, though that was with HTTP functions.

Are you absolutely sure a CORS header that should definitely be present is absent? And this is Wix’s fault (as I say it does happen)? If it’s definitely a bug, you can try posting on this forum with [BUG] in the title or you can try your luck with support.

This is an old post and is no longer relevant. I’m going to close it. If this problem happens again, you should contact wix support.
