I had the same problem and found the solution.
Here is solution:
Add to your wp-config.php file in your main wordpress folder these lines:
define( 'WP_CONTENT_DIR', dirname(__FILE__) . 'wp-content' );
define( 'WP_CONTENT_URL', 'http://example.com/wp-content' );
Important 1: you should put it before this line:
if ( !defined('ABSPATH') )
Important 2: when you define WP_CONTENT_DIR you MUST NOT use
Maybe it will be needed to turn on all plugins again. I suggest you to make backup of your database before changing wp-config.php.
Try it and give feedback if it helped you.
