Snapfour on "Google PageSpeed Insights: autoptimize files not compressed?"

Hi,
Pagespeed has asked me to compress autoptimize_<heap of numbers and letters>.js
I disabled static delivery (option "Save aggregated script/css as static files?") as recommended above and it fixed the Pagespeed problem.
However now every time I goto my site it pops up with a window asking to login. I tried on a few pc with different IP address and it still comes up even when logged out of admin. When enabling static delivery again the login problem goes away but Pagespeed is asking for compression again.
Im using Autoptimize along with WP Super Cache
Any ideas guys?
