Hello,
Thanks for your reply. When you say change the code in WP… Do you mean me physically going into the file I.e. FileZilla and editing the code in say notepad or going into the file on WordPress and editing the code manually?
Yes.
If you did not edit any code in files in wp-content/themes/xstore then don’t worry about update. If you did then you will lose them after the update.
Regards
