Thank you for reaching out and reporting this.
The above is caused by a bug affecting some of our customers. It was introduced with a release Sunday evening (CET). We've fixed it with a new deploy this morning and we no longer see the error described.
Other of our sites have a similar issue - www.b.dk and www.business.dk.0
Thanks for the details and fix.
Is there any way to use versioning?0
Hi Cookiebot. I continue to see this problem, have I to do something more maybe?
EDIT: I'm sorry, I've solved the problem. It's necessary to empty cache of the browser. Done this, the problem disappears. Thanks a lot anyway.1
This may be a caching issue, what website are you seeing this behavior on?0
