Website is broken

Selecting:
By default files saved are static css/js, uncheck this option if your webserver doesn’t properly handle the compression and expiry.

Score of the website is low.

Unselecting it breaks the site.

I had a quick look, seems like Autoptimize isn’t currently used?

I am already using it. Please check it once. I have installed and configured it.

OK, I now see it is active (saw Swift Performance Lite before). Now what is your question exactly?

When I Select the option:
By default files saved are static css/js, uncheck this option if your webserver doesn’t properly handle the compression and expiry.

Score of the website is low.

When I Un-select it my website breaks.

yes as I mentioned in another thread I like using AO but in this site its now working as expected. Maybe you can help.

please see the waterfall here.. the images are getting blocked so time exceeding.

-> non-static means PHP ensures compressing is done & correct cache headers are sent. if things break you likely have *something* blocking PHP-scripts from being executed from certain directories (wp-content/cache in this case)
-> static means your webserver config should take care of compressing & cache headers
-> if compressing/ cache headers for AO’d files are not OK when using static, you should tweak your webserver configuration
-> images are considered low priority by browsers, even more so if you’re using a lazyload solution (a3 lazy load in your case)
-> moreover images are loaded from an amazon s3 location, but s3 is more about data storage then about CDN’ing so it might be slower then expected (see https://deliciousbrains.com/shouldnt-serve-assets-s3/)

hope this helps,
