ie8 bootstrap wordpress glyphicon

you need to download bootstrap locally for this to work. ie8 will not work using CDN.

http://getbootstrap.com/customize/

you will have a zip file container all files needed.

On my case I load it all on my custom plugin and I copied the whole bootstrap directory including the fonts to my plugin directory.

my main plugin class. i’ve got a helper method load_file the uses wp_enqueue_style

....
            $this->load_file(self::slug . '-script1', '/js/bootstrap.min.js', true);
            $this->load_file(self::slug . '-style4', '/css/main.css');
            $this->load_file(self::slug . '-style5', '/css/bootstrap.min.css');
            $this->load_file(self::slug . '-style6', '/css/bootstrap-theme.min.css');
....

header.php – it should be after wp_head

        <?php wp_head(); ?>
