(1) The visualizer still asks for HTTP authentication, while the whole web management uses a new log-in dialog. This means that I need to log-in twice: once using the log-in dialog (to enter the web management) and then for the second time
when I enter the visualizer.
(2) The visualizer now doesn’t display the RabbitMQ logo. Problem is that the logo is (well, used to be) the only way how to leave the visualization screen and switch to another web management screen. Is it a bug or a feature? ;-)
Re: Can NOT start 2.8.6 (using R15B03), Can start 3.0
Although Rabbit will
upgrade its Mnesia schema to newer versions when an upgrade is first installed, that code doesn't IIRC do the reverse. Assuming there's nothing in your Mnesia that you want to keep you should try blowing them away and then starting 2.8.x. If there is stuff there you want to keep, reinstall 3.0, export the stuff for safekeeping, then trash Mnesia and go back to 2.8.6.
Alternatively you could play with the environment settings to put Mnesia somewhere else for one of the versions...
