Thank you for writing in, the problem on your site is you updated the Cornerstone to the latest version (3.5.2) but leave the X Theme behind (6.1.6).
Please update your X Theme to the latest version (6.5.2).
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.
2) Add a
width property to your image tag, so it will have a specific width.
<img src="URL HERE" width="200px" height="auto" />
3) Please follow one of the methods here, and if none works please contact your hosting, they might not allow the users to change the PHP settings on their own.
