You're currently using Platform Pro version 1.5.3, can you please update to the latest version, be sure to perform a backup as a precaution. Once updated, check to see if you can change your sidebars width.

Once installed, record your issue, upload it and in your reply, provide a link to the screencast.Go to the full post
