Now that you’ve mentioned it I noticed there’s a new version from yesterday.
I’ve updated the plugin, but still get the following error:
[07-Feb-2019 09:16:42] WARNING: [pool {USERNAME}] child 6583 said into stderr: "NOTICE: PHP message: PHP Warning: strpos(): Empty needle in /home/{USERNAME}/public_html/wp-content/plugins/lazy-load-optimizer/src/Frontend/Frontend.php on line 221"

By the way I’m using PHP v7.2.9
