Overview
Some sites need specific PHP versions. Newer supported PHP versions generally run faster and are more secure, but older plugins/themes may require older versions.
How to change PHP version
MultiPHP Manager (common)
1) cPanel → MultiPHP Manager
2) Select your domain
3) Choose PHP version
4) Apply
PHP Selector (CloudLinux environments)
1) cPanel → Select PHP Version / PHP Selector
2) Choose version and apply
Common PHP settings (if available)
- memory_limit (helps heavy plugins/imports)
- max_execution_time (helps long operations)
- upload_max_filesize and post_max_size (uploads/imports)
- max_input_vars (large forms/page builders)
Safe change process
1) Backup site
2) Change one thing at a time
3) Test:
- Frontend pages
- wp-admin login
- Forms/checkout
4) Check cPanel → Errors if something breaks
If site breaks after PHP change
- Revert to previous version
- Update plugins/themes
- Disable conflicting plugin
If you need guidance
Provide:
- Domain
- Site type (WordPress/WooCommerce)
