Sidebars dissapear in current theme and cannot get layout right

Hi, using the latest version of the plugin and when activated all my sidebars dissapear from my theme. any ideas?

my site is https://jobldesign.co.uk the car-sales name page is https://jobldesign.co.uk/car-sales. by the way is there a way to change this permalink?

Also is there any way you could suggest best way to use css to get a inventory layout like this kind of thing? https://www.eshartleygroup.co.uk/motorhomes/showroom&type=Motorhome&saletype=Used

Also the price doesnt show on the inventory list. I am just guessing this is just maybe a CSS issue as the formatting doesnt seem right.

Thanks
