8/10 nightly issues

Just upgraded my site to the 8/10 nightly and see this at the top of my admin window –

Warning: main(/usr/www/users/jgreene/wp/wp-content/plugins/): failed to open stream: Unknown error: 0 in /usr/www/users/jgreene/wp/wp-settings.php on line 87
Warning: main(): Failed opening '/usr/www/users/jgreene/wp/wp-content/plugins/' for inclusion (include_path='.:/usr/local/lib/php') in /usr/www/users/jgreene/wp/wp-settings.php on line 87

On the home page of my site I get this:

Warning: main(/usr/www/users/jgreene/wp/wp-content/plugins/): failed to open stream: Unknown error: 0 in /usr/www/users/jgreene/wp/wp-settings.php on line 87
Warning: main(): Failed opening '/usr/www/users/jgreene/wp/wp-content/plugins/' for inclusion (include_path='.:/usr/local/lib/php') in /usr/www/users/jgreene/wp/wp-settings.php on line 87

All my plugins are off and would need to be activated… I have no idea what this error means and would appreciate any help here.
Thanks!
