Hi I was wondering if heavily customised themes will be affected when your Jobroller software is updated? I just saw a video on You Tube where the guy lost most of his site when he updated?
If you have made modifications to the core theme files then yes an update will result in loss of these changes as the theme files are essentially replaced with new ones. What we strongly recommend for people who are planning to customize any of our themes is that they create a child theme which will prevent this from happening. You can read more here about customizations. Thanks.
