A slow WordPress site can be caused by the website itself, the hosting resources available to it or a mixture of both.
Start by thinking about what changed recently. A new plugin, theme update, large image upload or custom code change can all affect performance.
Useful checks include:
- Deactivate unnecessary plugins.
- Test whether the site is faster with a default WordPress theme.
- Optimise large images.
- Check whether caching is enabled.
- Review recent changes to
.htaccess. - Check the PHP version used by the site.
- Look for large error logs.
- Check cPanel resource usage if your hosting account provides it.
Plugins are a common cause of slow WordPress sites. Even well-known plugins can slow a site down if too many are installed or if one is badly configured.
Large images are another common issue. Resize and compress images before uploading them where possible.
If the site is still slow after basic checks, contact support and tell us what you have already tested. We can help check whether the problem appears to be hosting-related or website-related.
