Front works fine - both display and financial side. BO works fine (mostly*) - just this error box telling me something is wrong, but not what, other than I should refresh the page and the error is a 'problem on our side'. Refreshing makes no difference and hasn't for days.
* Some of the dashboard reports/messages continuously spin but never update; that's all the parts of the Activity Overview. But that has never worked since installing a clean v8 (then updated to .02 and now .03). They don't affect operation and as they haven't worked for months, I assumed this message is something else because it is new, a few days now.
So yes, this one message states there is a problem but not what.
