#1

I have a curious situation: i have updated an old installation with this command and added WP Supercache: ee site update example.com --wpsubdomain —wpsc The supercached files are being delivered through PHP:
WP-Super-Cache: Served supercache file from PHP Files are beeing generated in wp-content/cache/supercache/

Any suggestions where to look?

supercache has several options on its settings page - try using the highest option. However, I’m not sure it will work well with the NGINX rules. Try it!
