Thanks! We got it!
Just one thing: it first failed as I copy/paste text from you blog, some quotes were uncorrect.
From you blog, I got: a:1:{s:9:”keymaster”;b:1;}
And I had to use: a:1:{s:9:”keymaster”;b:1;}
Don’t know if the difference is really visible on this page.
The steps I did:
* install bbpress without setting any WP integration,
* access the dashboard as admin, and configure the WP integration, but I did not touch the roles mapping,
* install and configure the bbPress WP plugin,
* relog in bbPress with my WP admin account…
and then I was not able to access the dash board…
Any idears?
