Theme CSS can’t be removed! It includes styles for the different WPBakery elements, for different types of product, header, blog layouts and there is no way to remove the part of styles at this moment.
1) Connect your hosting provider to fix the problem with your SSL certificate http://prntscr.com/pghuv4 because we can’t test your site speed using GTMetrix or optimize images directly from your site http://prntscr.com/pghw4k
2) Reduce the page size http://prntscr.com/pgho9w using optimized images https://gyazo.com/c07ba78a03686377a89f5d2f7ca32eb5 Why do you use such a huge image for such a small block http://prntscr.com/pgi42k ? The optimized image takes much less.
3) Check the list of enabled third-party plugins and remove plugins that you don’t use.
4) If you need advanced help with site optimization contact WPKraken team because our support does not include personal optimization service.
