Hello Qtwrk,
I did lot of search and i found plugin iTheme Security has problem with Sppedlite.
I just: Unchek “Disable PHP Plugin”.
Now i don’t have error 404 and also the lazy load for images in my home work fine.
At this moment all work perfect.
My question is: (Unchek “Disable PHP Plugin”.)
Does this option have negative effects ?
Thank you.
