How to keep WordPress up to date
Just make sure you’re using at least WordPress 5.5, and that you’ve clicked “Enable auto-updates” for all your plugins and themes:
That’s all it takes — WordPress will then automatically update everything, and send you a message each time it does so.
If you do this, you can almost certainly ignore the rest of this page — but it has answers to some common questions we’re asked about WordPress updates.
Why would hackers target me, even if my site does use outdated software?
People are often surprised that their site might be attacked, asking: Why would they target me? Why would my small site be attacked by criminals when it contains nothing worth stealing? That question makes sense in the physical world, but things don’t work that way online. Hackers can use even a small site to send lots of spam, distribute malware, infect site visitors with viruses, and worse. It doesn’t matter how big or small it is.
It’s easy for hackers to use Google to get a list of every site on the internet that runs a WordPress plugin or theme that might contain a security bug. They then use automated software to attack all of those sites, one by one, in the hope that the site is still using an old version. They don’t care if it takes weeks, months or years: they’re using stolen computer time anyway, and no human intervention is required to eventually try every last site, no matter how small it is.
Don’t updates cause problems?
If you think “I don’t trust updates, so I won’t update my site software for a while because I’m concerned about compatibility”, you’re setting yourself up for trouble unless you have a specific plan to apply the update in the very near future (by which we mean days, not weeks). Otherwise you’ll just get further and further behind; updating will become harder and harder with more risk of compatibility problems, and you’ll be even more likely to be “hacked” every day.
If you’re concerned about compatibility, you can make an extra backup right before a major update, and you can easily restore that backup in our control panel if there’s a problem. The type of problems potentially caused by updating are far less severe (and far more easily fixed) than the security problems potentially caused by not updating.
But aren’t most hacking attacks more complicated than this?
No. A surprising number of our customers read elsewhere about WordPress hacks, then write to us asking if their site is vulnerable... but when we check, we see they haven’t updated old plugins and themes on their site for months or years. We also see people who install complicated security plugins but don’t update WordPress itself.
This suggests that it’s not obvious how sites usually get hacked, and we want to correct that. So here’s some more annoying text:
Not updating a plugin, or theme, or WordPress itself, is the same thing as not applying security updates to your own computer. When your computer tells you there’s an update available, you (hopefully) install it right way to keep “hackers” out. You should do exactly the same thing with WordPress.
So please: Enable automatic updates as the section above describes. If you prefer to do it manually, always install updates every time you see that they’re available (and make sure you login to WordPress dashboard often to check). Remember that “security plugins” are not a replacement for keeping your site updated (in fact, at least one of the more popular plugins intentionally doesn’t block new security hacks for 30 days unless you pay them a monthly fee, making it almost useless).
By the way, if you’d like an independent confirmation of the idea that most WordPress security problems are a result of outdated themes and plugins, and that updating those fixes it, take a look at the blog of WordPress security company WordFence. You’ll see that the majority of problems they describe have a description that ends like this:
Two other thoughts about WordPress security and updates
By the way, if someone tries selling you a “premium” WordPress theme or plugin that doesn’t have automatic update notifications, you should avoid it. The only way to keep these secure is to return to the original download site from time to time to check for security updates, which few people ever do. Premium themes without automatic updates are a major security risk.
Finally, you should completely delete any plugins or themes you don’t use. Hackers can take advantage of some security bugs even if the plugin or theme is deactivated. If you’re not going to use it in the future, it shouldn’t be there at all.
