Reply To: Sidebar in Woocommerce shop not keeping its settings.

Hi Jay

Using our demo site, I have tried to recreate this and cannot recreate the issue you are seeing.

In the customizer; if you set the sidebar width to 0 or save it with an empty value, the sidebar will default to the 28% default width on the live site.

Please could you let me know the URL of your site and I will be able to take a look and see if there is anything that could be causing this.
