This is a somewhat obscure use-case but it appears that the Members plugin throws errors is it is deployed to a new site without an tables it tried to insert
'members_db_version' key into
Adding the following code at the top of
/members/includes/update.php solves the problem:
if ( defined( 'WP_INSTALLING' ) && WP_INSTALLING ) return;
I can work around it by putting the code into my must-use plugin loader, but I thought you might want to know.
