okay.. i've scoured the web and google fu'd till exhaustion.
this is all being done on my dev site (clone of production btw.)
i've created my db's
tried to put shardb-admin.php in mu-plugin folder - no workee sooo
i put it in shardb-admin.php in plugins and that worked
i ran the global migration and then sites
that seems to run successfully...
sooo when i move db.php to wp-content poof! i get redirected to the login screen and there's nothing in my error log or debug that seems to indicate what's going on.
i think its not finding the right tables/blog #'s now in my sharded db
entering my password doesn't work.. the main site has a blank screen. i've got nothing more to go on in the instructions. i am using an env.php... but everything works until i drop db.php in wp-content.
