How do I start using this plugin?

Hi Truong.
Yes, I did.
I'm trying to use on localhost, so I extracted at plugins folder, but it doesn't appears on installed plugins list.

I tested on production server and it works, but I still need to make it works on localhost.
Any idea?

Hi,
I added this line define('FS_METHOD', 'direct'); on wp_config and it worked. I don't know why, but it solved my problem.

But another one. I tried to add plugins directly on theme. Meta Box works, but Term Meta returns:

Warning: include(/var/www/html/wp-content/themes/my_theme/metabox/mb-term-meta/mb-term-meta.php): failed to open stream: Permission denied in /var/www/html/wp-content/themes/my_theme/functions.php on line 93

Warning: include(): Failed opening '/var/www/html/wp-content/themes/my_theme/metabox/mb-term-meta/mb-term-meta.php' for inclusion (include_path='.:/usr/local/lib/php') in /var/www/html/wp-content/themes/my_theme/functions.php on line 93

Any idea?
