Hi Luke, we are using litespeed cache, while this plugin helps in enhnacing site performance, we indeed have faced issues with litespeed in the psat as well and had kept it disabled for a good amount of time only to re-enable again to gain some performance advantage.
For some reason, litespeed only affects our site, my friend is also using your theme and using litespeed cache and there is no problem reported on his site.
As for the 2FA, I have extended grace period now, it won’t bother you for 15 days from today.
