Incorrect Usage of ABSPATH which breaks sites using custom WordPress install paths

[timnolte]

The code here:

https://github.com/BoldGrid/library/blob/master/src/Library/Start.php#L181-L187

doesn't work properly to determine the actual WordPress path when WordPress Core is installed in an alternative place. This causes major plugin broken UI issues as CSS & JS assets can't be loaded properly. This should be using WordPress Core methods for determining paths & URLs.

The issue was originally reported here: BoldGrid/boldgrid-backup#546

FYI, doing some testing and what is working is the following code:

                if ( ! empty( $configs['libraryDir'] ) ) {
                        $configs['libraryUrl'] = plugin_dir_url( $configs['libraryDir']  . '/src' );   
                }
