Hi Olga,
Thank you, that does look a lot better now.
Unfortunately the categories boxes still do not look like the main website, please see the example images:
Main site: https://www.dropbox.com/s/ms8hooilccggj93/Untitled.png?dl=0
Staging: https://www.dropbox.com/s/p8znvfkhucr0zgr/staging.png?dl=0
Regarding the other issues – can I now backup the xstore configuration and use this to import it on the main website when I update the theme there? Will this fix any of the issues I faced with the staging site, prefooter area in the header etc?
I also notice that my top header and the bottom footer data is not the same as the main website, is this overwritten when the theme gets updated?
