Hi, @lclarke
No, I couldn’t generate any domain key because my hosting wasn’t supporting it. I talked about this with the support team of my hosting provider.
I’m not sure if the standard queue was working (assuming it’s the same as before) because none of my newly uploaded (2 to 3 days) images were optimized.
In the end, I deleted the plugin and left LiteSpeed on the server level. I was having other problems with it and the image optimization was the last straw for me.
