I got an email today from my parents, that the navigation in their website/shop (Prestashop) is broken and they get an error if they click it. I had a look, and it turns out they manually deleted at least 2 categories.
How would i handle this? I am too busy to help, and the only local "computer guy" doesn't knows anything about Prestashop. When i told them to ask any questions at the official Prestashop forums my parents told me they don't know "the slang" and wouldn't understand anything. What is your advice in such situations?
