Hi I updated to the latest theme / wp bakery / woo commerce etc and when i add a new
product and go to select a default or alternative from the layout option i submit but the change isnt registered and it still shows the old value ?
Please deactivate all the plugins not related to the theme and check the issue, disable the cache plugins first of all, and as soon as you have made any changes, refresh the browser cache as well.
If the problem remains, please provide your site admin access to the private area.
