 * Hi,
 * When I activate the plugin, I receive the following PHP warnings:
 *     ```wp-block-code

 * Hey [@jason6666h](https://wordpress.org/support/users/jason6666h/)! 👋
 * Could you please disable other plugins and check if these warnings are no longer
   logged? Then, re-enable each plugin one by one to identify with which one triggers
   these messages. It’s possible that another plugin is using the same constant 
   name from this PHP library. Thanks!

 * Thank you for your reply. It seems to be a conflict with the Flying Image plugin,
   which I use as a lazy load feature.

 * Is it possible to load MeowLightbox only on Gutenberg pages in the blog page?
 * I also found that using the Optimize More! plugin to delay loading can cause 
   this error to occur.
