Strange red error in Data Manager

As of today, I get a red line underneath every field in Data Manager (the Data Grid), Live Mode.

I can see nothing wrong, but every field displays an large error, as by screen shot.

Hi,

I opened the URL and couldn’t see any red lines or errors, does the problem persists?
Did you manage to fix it?

Thanks. Today, it is gone, spontaneously.
