1 there is and error when accesing the page:
WebSocket connection to ‘wss://public-api.wordpress.com/pinghub/wpcom/me/newest-note-data’ failed: Error during WebSocket handshake: Unexpected response code: 403
What it is regarging to? how to disable it?
2 On loading there too many css requests. How can I optimize it? Or how to add async or defer atributes to them? I want too speed up page loading because its too slow at first load, later cache is doing it’s job but even then it can speed up a little with proper request priority.

2) You can use cache plugin and combine/minify CSS, JS, HTML. Also, disable all the plugin that you don’t use. For example, do you use 360 products? If no then why do you keep Smart product viewer plugin enabled? Disable Revolution slider scripts for those pages where you don’t use the slider shortcode http://prntscr.com/m8gj6g
If you need help with advanced site optimization you can contact Codeable team because site optimization service is outside the scope of our support and we don’t have such specialists.
