Rigth now there is no problem with Plugin Speed Optimizer from Siteground, I’ve excluded your shortecode from the lazy loading and the codes displays without problems.
Could you please check at your side using Astra theme and your the plugin, because the error comes from the theme conflict
My plugin cant have any issues with any themes because my plugin dont use any specific functions related to the themes. So Astra or any other themes – not important – my plugin is universal.
But if your theme or any other plugins blocking images as your plugin for cache then issues appearing.
this issue
