Hello @edowahanasurya,
Greetings. Hope you’re doing good.
Well, I have just checked your site and also the screenshot that you have provided and couldn’t find that warning on your site now. Have a look, please:- https://d.pr/i/xASHSf
However, we have already brought the fix for this warning and also released it in our recent versions. Moreover, if you will find this warning again, I suggest you, please try doing the following: To regenerate assets, you can go to wp-admin -> Essential Addons then, switch to the ‘Tools’ tab and hit the ‘Regenerate Assets’ button. Check out this screenshot: https://d.pr/i/iBccDw
Also, make sure to Regenerate Files from wp-admin -> Elementor -> Tools -> General as well. Check out this screenshot: https://d.pr/i/N6WC1d
And also clear your cache through your caching plugin and clear the cache from the server end as well.
Hopefully, you will not get that warning anymore. Let me know how it goes.
Thank you!
