I'm trying to build a plugin and having problems loading the js. I have added this code to load the file but it doesn't seem to:
plugins_url( 'clock.js', __FILE__ );
I am also seeing this error:
The plugin generated 6 characters of unexpected output during activation. If you notice “headers already sent” messages, problems with syndication feeds or other issues, try deactivating or removing this plugin.
How do I deal with it please?
