First of all thanks for your time and your effort creating this awesome framework.

I had installed Wordpress with yeoman wordpress generator. The wordpress installtion folder is different from the content folder.

Wordpress version : 4.0
CMB2 version : 2.0.0-beta
Localhost enviroment : Windows 7 SP1, XAMPP 3.2.1

wp-config.php

if (!defined('WP_SITEURL')) {
define('WP_SITEURL', 'http://' . $_SERVER['SERVER_NAME'] . '/ai/cms');
}
if (!defined('WP_HOME')) {
define('WP_HOME', 'http://' . $_SERVER['SERVER_NAME'] . '/ai');
}
if (!defined('WP_CONTENT_DIR')) {
define('WP_CONTENT_DIR', dirname(FILE) . '/content/');
}
if (!defined('WP_CONTENT_URL')) {
define('WP_CONTENT_URL', 'http://' . $_SERVER['SERVER_NAME'] . '/ai/content');
}

I tried to add a metabox and the resources do not load. Specifically the cmb2.min.css, jquery.timePicker.min.js, cmb2.min.js. I get a 404 error.

The problem occurs on the resources path. A trailing slash is missing at the end of the WP_CONTENT_URL.

It is http://localhost/ai/contentthemes/ai/inc/admin/cmb2/css/cmb2.min.css?ver=4.0 and should be http://localhost/ai/content/themes/ai/inc/admin/cmb2/css/cmb2.min.css?ver=4.0

If I add at the end of WP_CONTENT_URL a trailing slash is working but all permalinks have two trailing slashes.

Thanks in advance.
