The Development section includes the following settings:

Setting	Description	Values	Default
Standardized Hooks - Debug Mode	The Standardized Hooks system’s debug mode helps to troubleshoot hook issues. For more information, read our Guide to Standardized Hooks - Debug Mode documentation. If instead of this setting, you use the `/var/cpanel/debughooks` file to enable debug mode, your locale may revert to the English defaults for JavaScript elements. To fix this problem, run the `echo -n > /var/cpanel/debughooks` and `/scripts/restartsrv_cpsrvd` commands to disable debug mode and restart the `cpsrvd` daemon. Important: If you enable this setting, it also enables debug mode in the cPanel interface. This severely impacts the loading and performance of the cPanel interface. We recommend that you disable this setting when you do not need it.	Debug mode is off. — The system does not display debug information or log it to the error log. Debug mode is on.
