how to troubleshoot?

Hi,

Our site was doing good – we were getting consistent A and Bs on gtmetrix, and decent scores in Google pagespeed (85, etc).

It must have a been a plugin update, but now we are getting c, D, and sometimes F on gtmetrix – and we are getting in the 30’s on Goggle page speed.

Using chrome inspect, I can’t identify and errors (js, etc).

It seems that speed is effected when JS Minify and JS Combine are both active in litespeed.

Any suggestions on the quickest/easiest way to identify what might be causing the issues?

Thanks for any help.
