The principal PHP file in "Mega Lazyload" v. 2.1.0 is loaded by WordPress automatically on each request
Please take the time to fix the following:
  • Text Domain: The text domain must be the same as the plugin slug, although optional since WordPress version 4.6
  • Main file name: It is recommended to name the main PHP file as the plugin slug ("dmo-spacer-gif-generator.php" instead of "mll_sgg.php")
  • Description: If Twitter did it, so should we! Keep the description under 140 characters (currently 280 characters long)
