In version 3.13.0 the error message “Oops… there was a problem during the request. …” always appears on top of the Dashboard after I woke up my laptop. I assume the reason is that the Wifi connection needs more time to reestablish.
It would be great if I could close that message, since everything (including Ajax like Visits in Real-Time) actually works without problem. Alternatively, the message could simply disappear after a few seconds.
