Hi
I am also having this timeout error when trying to access the toolbox page settings on ls cache wp admin area. My browser will hang after a while. The page will not load and shows blank page on browser.
I installed Ls cache plugin a week ago and it is working very well. My Google pagespeed increased from 21% on mobile to 90%. I was previously using WP Rocket. But this toolbox not loading is an issue for me.
