Hmm.
I’m a SiteGround hostee, and I am running their SG Optimizer plugin, but I’ve also not actively changed/enabled any of the more advanced settings. i.e. no minification or combining in the front-end options etc.
A bit of Googling doesn’t turn-up anything for SG Optimizer and dashicons as a problem.
The more I think about this, the more I wonder if it’s ever worked in the front-end?
Some more Googling shows that many WP installations are forcing dashicons in the front-end with snippets like this:
/********************************************************/
// Adding Dashicons in WordPress Front-end
/********************************************************/
add_action( 'wp_enqueue_scripts', 'load_dashicons_front_end' );
function load_dashicons_front_end() {
wp_enqueue_style( 'dashicons' );
}
Thoughts?
