CR Servers supports multiple PHP versions (5.2 through 8.5) on our shared hosting platform. You can select a different PHP version for each of your domains directly from your SiteWorx control panel.
Step-by-Step Instructions
- Log in to your SiteWorx control panel at
https://your-domain:2443/siteworx - Navigate to Hosting Features → Domains → Manage from the side menu
- Click the pencil icon (✏️) next to the domain you want to modify
- In the PHP Version dropdown, select your desired PHP version:
- system-php — The server default (PHP 8.2)
- PHP 7.4 through 8.5 — Select the specific version your application requires
- Click Save
The change takes effect immediately. Your website will start using the new PHP version right away.
Which PHP Version Should I Use?
- WordPress: PHP 8.1 or 8.2 recommended (WordPress 6.x requires PHP 7.4 minimum)
- Joomla 4/5: PHP 8.1 or 8.2 recommended
- Joomla 3: PHP 7.4 or 8.0
- Drupal 10: PHP 8.1 or higher required
- Custom applications: Check your application's documentation for compatibility
Troubleshooting
My site shows a blank page or 500 error after changing PHP version:
- Your application may not be compatible with the selected PHP version. Try reverting to the previous version and check your application's requirements.
- Common issue: older plugins or themes may use deprecated PHP functions. Update your CMS and plugins to the latest versions.
