Was trouble-shooting a plugin. The author suggested wp-content and all files under needed to be chmod to 755.
Did that and BAM...broke everything.
Warning: opendir(/var/www/wp/wp-content/mu-plugins) [function.opendir]: failed to open dir: Permission denied in /var/www/wp/wp-includes/load.php on line 428
Line 428 of load.php is:
if ( ! $dh = opendir( WPMU_PLUGIN_DIR ) )
Obviously, my permissions under wp-content are all messed up...how do I get them back?
