Is there any way to hide the Options page?

Hey.

Sorry for the late reply.
I thought I receive a notification, when somebody open a thread.

You can do this.
1. Open the file hello-dolly-for-your-song/hellodollyforyoursong.php
2. Go to line 23 : add_action( ‘admin_menu’, ‘hdfys_show_options’);
3. Add 2 slashes before the command (//)

Now the Options page is not visible anymore in the admin navigation.
But this is a modification, you must do it after every update.

Best Regards
Marco

One additional note.
If you have disabled the options page in the navigation, you can use the option page nevertheless.
Just call the following URL directly.

/wp-admin/options-general.php?page=hellodollyforyoursong.php
