If you’ve got a WordPress site that was built years ago and you’ve not really touched it since, WordPress 7.0 might feel like one of those updates you’d rather ignore. When you don’t have ongoing support from your developer, updates feel risky.
You press a button and hope the whole thing doesn’t fall over.
But this update is a big one, it may affect your current site if you do that update. and it’s worth knowing what it means for you before it lands.
Your site probably won’t suddenly break, but older setups are more fragile
The biggest thing is that WordPress 7.0 needs a newer version of PHP than a lot of older sites are running.
If your hosting is still on an older version of PHP then WordPress will simply stop updating and leave you stuck on the older version. That means no new features and no access to the new AI tools and also means it is leaving your site vulnerable to security attacks that will no longer be patched.
If your site uses an old page builder, a custom theme from 2016, or plugins that haven’t been updated in ages, they’re the ones to watch.
If your site uses:
- Old versions of page builders (Elementor, Divi)
- WooCommerce extensions
- Membership or LMS plugins
- Classic themes from years ago
…these are the ones most likely to misbehave on newer PHP versions. Not because they’re “bad”, but because they’re complex and haven’t been updated to match the new environment.
This is why I always test older sites in a safe staging area first when performing a major update. It lets me see what will break before anything touches your live site.
AI is now built into WordPress, but you don’t need to spend a fortune
WordPress 7.0 introduces proper AI support. Not the gimmicky stuff you see bolted onto random plugins. This is a single connection that lets your site talk to OpenAI, Google Gemini or Claude without needing five different plugins all doing the same thing.
The important bit is this. WordPress doesn’t give you free AI usage. You pay the provider directly, but the costs are small if you choose the right model.
Here’s the simplest way to keep costs down.
OpenAI
Cheapest for general text. Ideal for blog drafts, product descriptions and rewriting content. Their lower tier models are pennies to run.
Google Gemini
Cheapest for mixed content. Good if you want AI to understand images as well as text. Their Flash model is designed to be low cost.
Claude
Brilliant for long content and detailed writing. Not the cheapest, but great if you need pinpoint accuracy and structure.
For most small business sites, OpenAI or Gemini will give you everything you need at the lowest cost.
So what should you actually do next
If your site is older and you don’t have anyone maintaining it, here’s the straightforward plan.
- Check your PHP version in your hosting panel (sometimes called cPanel or Cloud Panel). If it’s below 7.4, it needs updating.
- Look at your plugins. Anything not updated in the last year is a risk.
- Decide whether you want to use the new AI tools. And let’s face it, if you haven’t updated your site for a while, you probably won’t need them… but If you do, look carefully for pricing before connecting it with WordPress
- Don’t rush into the update. Let the first couple of minor releases settle before jumping in.
Your site won’t explode when WordPress 7 is released, but updating it does need a bit of care. WordPress 7.0 is safe, but your older plugins and themes might not be.
One thing is for sure, if you want to update your site in the next 6 months, you will need to update it at some point and an updated site will be much more secure and will continue to have security updates in the future… Patches for the older WordPress versions will eventually stop getting updates and will be more vulnerable in the future.
And if you’re thinking “I’m just going to leave it forever, what harm can it do”, that’s fine. Just remember that the ‘harm’ usually arrives at 11pm when your site stops working and you start Googling “why is WordPress angry with me”.
If you’d like me to check your site before you do any updates to WordPress 7.0, I’m only one message away. I promise not to judge your plugin list. Much.
