Did you apply a width to your logo as I suggested above? I don't see your logo having a defined width still. The value should be an integer only no
And I see your Cornerstone is up to date (3.5.4), but your X theme is a few updates behind (6.4.6). Please update your X theme to the latest version (6.5.5), to make sure this is not a compatibility issue.
Updating Your Themes and Plugins
Remember to clear all your caching features (plugin, server-side, CDN, and browser's cache) after updating so that the code from the latest release is always in use. This will help you to avoid any potential errors.
Hope it helps,
