Some modules require compilation and take longer to install. You can check the progress on the Task page.

PHP Functions Disabled

Some high-risk functions are disabled by default. To enable them:

Apps -> Operating Environment -> PHP -> Manage -> Parameter Tuning -> Disabled Functions

Remove the function names you want to enable from the list, then save. You can also edit disable_functions directly in the Main Configuration tab.

To switch versions for existing websites: Edit -> Basic Settings -> PHP Version.
