2. Select New Version: Click the dropdown next to Current PHP version and choose a version (e.g., PHP 8.1 or 8.2).
3. Recommendation: Use the highest version supported by your software (like WordPress) for security and performance.
4. Set as Current: Click Set as current to apply the change.

Step 3: Enabling/Disabling Extensions

1. Below the version selection, checkboxes list available PHP extensions.
2. To Enable: Tick the box next to the extension (e.g., zip, opcache, pdo).
3. To Disable: Untick the box.
4. Auto-Save: Changes are saved instantly as you click them.

Step 4: Modifying PHP Options (Memory Limit, Upload Size)

1. Click the Options tab at the top of the PHP Selector page.
2. Locate settings like:
   • memory_limit: Increase to 256M or 512M for heavy plugins.
   • post_max_size & upload_max_filesize: Increase for large theme or media uploads.
   • max_execution_time: Increase if scripts are timing out.
3. Click the value to change it; changes save automatically.

Common Troubleshooting

• Site Goes Blank: If a white screen appears after changing the PHP version, your code may not be compatible. Switch back to the previous version.
• Missing Extensions: If a plugin reports a missing module, check it in the Extensions list. If not listed, contact Jiinubi support.
