after successfully upgrading from 6.4 to 7.0, everything works fine except the performance graphs both for the host and guests (VMs and LXC-Containers). Mouseover displays some data, but nothing else is visible.
Do you have a solution for this strange behaviour?
I tried to delete website data via the firefox-function when klicking on the website information and got desperate, because on every other browser the graphs were working just fine.
