Hi @gransar!
The filter has been recently replaced by a new one:
jetpack_lazy_images_blocked_classes
We suspect that either your theme or another plugin in your site is still using the old filter, so we need to pinpoint which one is doing that:
1) try to temporarily deactivate all your plugins and check if the filter goes away. If it works, then reactivate each plugin one-by-one to find out which one is causing problems.
2) try to temporarily switch your theme to Twenty Sixteen and see if the problem persists. If the filter disappears, it means that your theme is using the old filter.
Once you find out what is using the old filter, you want to update the code accordingly.
Hope that’s all clear! Let me know how you get on 🙂
Hi! I found out the culprit was Elementor plugin. Is there anything I can do besides contacting their support? Thank you very much!

You’ll need to contact Elementor so they can update their plugin code to use the new filter. You can update it yourself if you’re comfortable editing plugin files, but it would be best for the plugin itself to be updated.
