Nice website! What happens when you update it?

By definition, business owners looking for a new website lack the technical skills to look “under the hood” of what they get. They can grasp the concept of a content management system, they recognise the name WordPress, but for the most part, they look at their website as the public would look at it, move around a bit and give their lowest-bidding web developer the thumbs up to go live.
A couple of months later, a major WordPress update comes along, with a flurry of updates to plugins and themes that must be made compatible. Most, if not all, of these updates contain bug fixes and security patches, so it’s really important to apply them. If left untouched, the website will gradually become more and more exposed and the online business will be in too much danger of being hacked.
“No problem”, thinks the hapless site owner, “All I need to do is click that Update button and my site will do the rest automatically”.
Famous last words…
