Hi Justin,
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 wp_options
before wp_options
exists.
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.
