Hi @neoli,
It looks like the PhastPress cache was cleared without WP Super Cache being cleared as well. That causes the CSS optimization to stop working.
Could you clear your WP Super Cache?
Other than that, it seems to be working. These are the remaining issues in GTmetrix:

Unfortunately, most of these can only be solved by reducing the amount of scripts on your page. For example, the external scripts on skimresources.com and flexlinkspro.com.
You might want to try disabling Jetpack image optimization and using PhastPress image optimization, because it seems Jetpack is not optimizing images very well.
And there’s a plugin that you’re using that generates a really huge (over 5 MiB) JavaScript file:
/wp-content/uploads/woos_search_engine_cache/guaven_woos_data.js
This should be avoided, but it’s probably difficult to do that without removing the plugin entirely.
