Introduction
PHP is the backbone of most modern websites, including popular CMS platforms like WordPress, Joomla, and Drupal. Using the correct PHP version is crucial for performance, security, and compatibility.
With Tublat hosting, you can easily change the PHP version for each domain or subdomain via the cPanel interface—no coding knowledge required.
Why Changing the PHP Version Matters
-
Security:
Newer PHP versions receive security patches that protect your website from vulnerabilities. -
Performance:
Modern PHP releases are often faster and more efficient, improving page load times. -
Compatibility:
Many plugins and CMS platforms require specific PHP versions to function properly. -
Future-Proofing:
Staying current reduces the risk of compatibility issues with updates to CMS, plugins, or server software.

7. Test Your Website
Visit your site to ensure it works as expected. Check core functionality, plugins, and themes.
Tips for Choosing the Right PHP Version
-
Use the latest stable version whenever possible for better speed and security.
-
Check CMS/plugin requirements before upgrading. Some older plugins may not yet support the newest PHP releases.
-
Avoid outdated versions (like PHP 7.3 or lower), as they’re no longer supported and may pose security risks.
-
Back up your website and database before making any major changes.
-
Test after switching to confirm that everything, including custom scripts, runs smoothly.
Troubleshooting Common Issues
-
White Screen or Errors After Update:
Switch back to the previous PHP version or check for incompatible plugins/themes. -
Option Missing in cPanel:
Some basic hosting plans may not allow manual PHP selection. Contact Tublat Support to enable the feature. -
Unexpected Behavior in CMS:
Ensure all plugins, extensions, and the CMS itself are updated to versions compatible with the new PHP. -
Performance Drops:
If you notice slowdowns, review installed plugins or scripts; sometimes the newer version may require optimized code.
Best Practices for Tublat Users
-
Regularly review your PHP version: at least every 6–12 months to stay aligned with security updates.
-
Keep backups: before and after switching versions to avoid data loss.
-
Use staging environments: if available, test the update on a staging site first.
-
Monitor site analytics and logs: for early detection of errors after switching.
-
Work with your developer: if your site uses custom scripts, have them review compatibility.
