I am reminded by my dashboard to update the Spirit wpmudev theme that I am currently using. from 0.4.1.3 installed to 0.4.1.5. However, it says clearly that any updates will erase customisations made to theme files, consider using child themes for customisations.
Can someone please explain to a simpleton like me how I would find out if I am using a parent or a child theme? AND if my use of said theme would class as customisations that will be affected by an update. My path so far has pretty much been to choose the Spirit theme and edit it in upfront and now I have my site. So this means I am using a parent theme and updating it will default my site back to the original spirit look appearance?
Thanks for all help, apologies to waste time.
