@wlpdrpat Preloading works for all public custom types (including builtin posts/pages) and it’s possible to exclude some CPTs via filter wpsc_preload_post_types
. Related to expired files, it’s possible that preload don’t remove them, but newer version of WPSC has improved function wpsc_delete_post_archives and it’s big chance that editing post will remove “all related pages”.
@csandreas1 I quickly checked your website and I don’t see JS errors now (and HTTP headers look good). It’s possible that was result of minification or something like this (Cloudflare or Clearfy plugin). Is it fixed now or you still experience this issue?
