That leads me to believe this isn’t an issue with Woo, but with the way that your theme styles these pages. It sounds like you’d want pages to be styled in full-width, but these pages aren’t styled like that.

I’d recommend reaching out to your theme developer for suggestions on how to modify the styling of those pages.

If they are unable to help, you might want to look into the possibility of:

1. Hiring a developer to make this style changes for you.
2. Looking for a different theme that better fits the idea you have in mind.

I’ll try taking a backup and changing the theme.
Yesterday, another issue also cropped up. While adding a product, suddenly the single product page stopped working and started showing 404 Page not found.

Normally when a 404 pops up, there was an issue with saving the product, or there’s a visibility setting somewhere to set to hidden.

Can you try resaving the product, and make sure the visibility of the product is set to public?

Glad to hear you are sorted. Have a great one!
