To access the PHP Settings page:

Configurable options
This section describes which PHP settings you are able to configure in the panel.
A changed setting will apply to ALL websites assigned to the specific SFTP/SSH user.

Increasing PHP values
Increasing PHP limits should be done carefully, as changes may affect website or server performance.
- A higher memory_limit can significantly impact performance, especially on shared hosting or lower-resource VPS plans.
- Other limits (such as max_execution_time or upload_max_filesize) typically have less direct impact but may still affect performance if set excessively high.
- If values exceed your server’s available resources, they may revert to the default values.
If higher limits are consistently required, consider upgrading to a plan with more resources, such as a VPS or Dedicated server.
