I installed and activated WP Minify.
I have 'debug' on in my config. When I load the site (local dev server) I get the warning:
"Notice: is_feed was called incorrectly. Conditional query tags do not work before the query is run. Before then, they always return false. Please see Debugging in WordPress for more information."
I still see multiple http request for js files in chrome dev tools.
This persist even when all other plugins are disabled.
My scripts are called in the recommended way: enqueued from the functions.php file.
