I am sure I changed nothing else. To recover I just deactivated plugin, restored plugin folder from a backup, activated, cleared caches and everything back to normal.

Alternative HTML minification does not solve it.

Thanks

you can see it on my test site: test.(mydomain)

I have reverted to 2.2.1 and problem gone.

Thanks, I do use Cloudflare but already have this feature turned off as per your very helpful FAQ section. ??

You were absolutely right. Though I don’t have other optimizations enabled, my pricing table plugin was doing that for some reason in a function called prevent_rocket_loader_script. I have tweaked the plugin so it does not do that and will report it to them.

Thanks a lot!

Do you have any other suggestions. The only things I updated recently are WP and Speed Booster Pack.
