Good day for all
I really searched SE for something like this but found nothing related.
It is a noob question really but getting answered will make me comfortable with myself :)
After setting the header section of a test plugin file I just put an echo statement.
When I activate the plugin the string of the echo gets displayed on the admin dashboard page as well as on the home page.
Is this common sense on WP or am I missing something ?
thank you a lot.
