Please help, Plugin Manager exploded my plugins!!

I tried to install it, and even though it’s supposed to be so very simple, it caused my plugins page to blow up. I have this code:

Warning: is_dir(): Stat failed for /home/duboisa/public_html/podsquad/wp-content/plugins/BAStats (errno=13 – Permission denied) in /home/duboisa/public_html/podsquad/wp-admin/admin-functions.php on line 978

Couldn’t open plugins directory or there are no plugins available.

I checked to make sure that all the permissions are set properly. I deleted all the plugin manager files, and even tried to load up a fresh version of admin-functions.php but it still gives me this error.
