Sorry for being slow to also report that on day one of this release I came up with the same install not working on localhost or on live server. Here now is my discovery & work around for what it is worth!
The error report I received from my localhost install indicated:
Fatal error: Uncaught exception ‘LogicException’ with message ‘Unable to find configuration file’ in . . .
I am not a coder able to interpret where the installer “stopped” but noticed that the config.json file was missing in the pulsecore/storage folder. In frustration I copied over from my config.json file from a v5.1 install - re ran the install again and it worked after refreshing the installer.
I then logged in using “my” password - not “demo”. It worked for me so hopefully for others this is an interim to test this release!
To you Michael: “In future can I ask you to indicate best way to report “bugs”, hiccups and possible interim solutions between releases so that we are all aware of possible gremlins. Do we use this forum? Do we use https://github.com/yuzoolcode/pulsecms-tracking/issues? Does sending you a personal email get through best?”
We cheer you on and together our shared experiences only enrich this great product! Thanks!
