 * Hello, and Happy New Year!
 * I have Pixabay Images installed and it works great, but the Pixabay Images Gallery
   plugin, upon activation, produces the following messages at the top of the page:
 * “Notice: wp_enqueue_script was called incorrectly. Scripts and styles should 
   not be registered or enqueued until the wp_enqueue_scripts, admin_enqueue_scripts,
   or login_enqueue_scripts hooks. Please see Debugging in WordPress for more information.(
   This message was added in version 3.3.) in …\wp-includes\functions.php on line
   3787
 *  Notice: Use of undefined constant script_loader_tag_handle – assumed ‘script_loader_tag_handle’
   in …\wp-content\plugins\pixabay-images-gallery\pixabay-images-gallery.php on 
   line 27″
 * And below the “Plugins ‘Add New'” title/button, there’s the normal message area
   with the following text: “The plugin generated 251 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.”
 * My site is running WP4.4 with a responsive theme…specifically, the theme is ‘
   raindrops’.
