Recently just started using W3TC again after the recent updates - looking good so far, but unfortunately Minify is causing me grief again. I'm getting the following error message with it enabled:
Recently an error occurred while creating the CSS / JS minify cache: No sources to serve.
When I go to the Minify URL (Just testing with JS files at the moment), I get the following error message:
HTTP/1.0 400 Bad Request
If I turn on WP_DEBUG I get no further information. I've got W3TC running on a Multisite installation of WordPress so I have no option to select which files get Minified manually. I assume the plugin finds files using wp_enqueue_script() and wp_enqueue_style() so perhaps I'm doing something wrong when defining those in my custom themes?
