Updating the PHP version in WordPress is a crucial process to ensure the performance and security of your website. Here is a quick and effective guide to perform this task easily.
Why is it important to update PHP?
Updating PHP not only improves the performance of your site, but is also critical for the security. The latest versions of PHP contain security patches and performance improvements that can make your site faster and less vulnerable to attacks.
In addition, many themes and plugins WordPress sites require specific versions of PHP to function properly. Failure to keep your PHP up to date can result in incompatibilities and errors on your site.
Benefits of an updated version of PHP
- Improved performance: The new versions of PHP are faster and more efficient.
- Increased security: Regular updates protect your site from vulnerabilities.
- Compatibility: Ensure that your plugins and themes are working properly.
- Better support: Older versions are less supported by the community.
Steps to update PHP in WordPress
Upgrading PHP may seem complicated, but it is a process that can be done in just a few steps. Here's how to do it safely.
1. Check the current PHP version
Before upgrading, it is important to know which PHP version you are currently using. You can check this from the WordPress administration panel:
1. Log in to your WordPress administration panel. 2. Go to "Tools" -> "Site Health". 3. Look for the "Information" section and there you will find the PHP version.
2. Make a backup copy of your site
Before proceeding with the update, it is vital to make a full backup of your site. This includes both the database and the site files. You can use plugins like UpdraftPlus o BackupBuddy to facilitate this process.
How to upgrade PHP from your hosting provider
Most hosting providers offer the option to change the PHP version from their control panel. Here's how to do it for some of the most popular providers.
Updating in cPanel
If your provider uses cPanel, follow these steps:
1. Log in to your cPanel. 2. Find the "Software" section and click on "Select PHP version". 3. Select the desired PHP version and click on "Save changes".
Plesk Upgrade
For those using Plesk, the process is similar:
1. Log in to your Plesk panel. 2. Go to "Websites & Domains". Select the domain you wish to update and click "PHP Settings". 4. Choose the new version and save the changes.
Verify your site's performance after the upgrade
Once you have updated PHP, it is essential to verify that your site is working properly. Check each section of your page and make sure there are no errors.
It is also advisable to use the Site health in WordPress to check for compatibility issues with themes or plugins.
Troubleshooting common problems
- White screen error: It may be caused by incompatibility between plugins. Disable the plugins one by one to identify the problem.
- Error 500: It usually indicates a problem in the .htaccess file. Try regenerating this file.
- Functions that do not work: Make sure all plugins and themes are up to date.
Final considerations before upgrading
Before proceeding with the upgrade, keep in mind that not all PHP versions are compatible with all plugins and themes. Make sure that the elements you use on your site are compatible with the new PHP version you plan to install.
Consult the documentation for each plugin or theme, and consider testing in a development environment before applying changes to your production site.
