Mark,
Your suggestion works!
Thank you very much!
I didn’t look at the usual suspects (me) instead was looking for the ghosts.
Will try your suggestion with Lazy Load by WP Rocket.
And I don’t have lazyload plugin installed.
This is really weird, as something messed up with my iFrame.
In wordpress for the page I have this:
<iframe src="https://inventasoft.com/pojmovnik" width="100%" height="500" align="center" frameborder="1"</iframe>
No lazyload, no data-src, no giff
Where did it came from?
I already installed it and checked but nothing showed up, just few recommendations, PHP version (we are on 7.2) and imagick.
