Now that you’ve prepared your site, it’s time to update PHP. The method you use may depend on your hosting environment:

1. Hosting Site Tools

Many hosting providers offer tools to update PHP directly from your hosting dashboard. Look for the PHP settings section and select the desired PHP version.

2. Updating PHP Using cPanel

If your hosting uses cPanel, follow these steps:

  • Locate the Software or Software/Services section.

What to Do If Something Breaks

In some cases, updating PHP may cause issues on your website. Here’s what to do if something breaks:

Steps To Take to Fix Your Website

Revert to the Previous PHP Version:

Suppose your website experiences compatibility issues, errors, or unexpected behavior immediately after updating PHP; the first step is to revert to the previous PHP version. Most hosting providers allow you to switch to the earlier PHP version from your hosting dashboard or control panel. This reversion can often bring your website back to its previous working state.

Check Error Logs:

To identify and address specific issues that caused the breakage, review the error logs on your hosting control panel or within the WordPress dashboard. Error logs provide valuable insights into the root causes of problems. Look for error messages, warnings, or notices that can guide you in troubleshooting.

Update Plugins and Themes:

Following a PHP update, outdated or incompatible plugins and themes are common culprits behind website issues. Ensure that all your plugins, themes, and WordPress core are current. Developers frequently release updates to address compatibility concerns. Update these components to their latest versions, which are more likely to be compatible with the new PHP version.

Contact Support:

If you find it challenging to resolve the issues yourself or the error logs are too technical to decipher, don’t hesitate to contact your hosting provider’s support team. They are well-equipped to assist you with PHP-related problems and can provide guidance and solutions. Be prepared to share details about your website, your updated PHP version, and any error messages or symptoms you encountered.

Consult a WordPress Developer:

If issues persist despite your best efforts and support from your hosting provider, consider seeking assistance from a WordPress developer or expert. Experienced developers can perform in-depth troubleshooting, identify complex issues, and implement custom solutions to get your website on track. While this may entail an additional cost, it can be a worthwhile investment in restoring the functionality and security of your site.
