I have a couple people who write articles from time to time sand after installing WP Block Admin they were unable to get to wp-admin anymore. Since we are only using three user levels on this site which are Admin, Author, and Subscriber. On install WP Block Admin is set to only allow Admin and Editor access to /wp-admin so you have to modify wp-content/plugins/wp-block-admin/wp-block-admin.php. Find the line like this:
$wpba_required_capability = ‘edit_others_posts’;
Change it to this:
$wpba_required_capability = ‘publish_posts’;
Once the changes are saved to wp-block-admin.php Admin, Editor, and Author will all have access to http://www.your-site.com/wp-admin. You could also modify the Roles and Capabilities of each user level but that is more complicated if your user setup is simple like ours.
