If for any reason content is not displaying correctly on your website, one of the first actions to take can be to flush the cache. This should only be necessary where files are replaced on the site without altering file names. CSS files can fall into this category on deployment.
In your Squixa portal, select Website > Content Delivery Networks and hit the big red button.
After hitting this button, it will take up to 10 minutes for the cache to clear.
If you have any concerns or problems still appear, please contact email@example.com immediately.
