I have the same problem.
Impossible to keep Global settings ?
I’m on last version of WP and i disabled w3 cache.
Many thank’s for your very quick answer 😉
I’m going to test it !
Same troubles… Gtmetrix and hosting are agree to tell us that plugin popup is very slow. More than 9 secondes to load completely !
Any solutions ?
Cool, many thank’s for your support 😉
