Add to Cart ends in 404 POST request (SPDY vs. HTTP2 on SSL)

You need to look at server error logs it seems https://ma.ttias.be/nginx-spdy-error-neterr_spdy_protocol_error/

Hi Mike,

thanks for your thoughts. I have activated the debug log since I could not find permission issues get logged. What I got was:

Maybe I am wrong but the get path seems odd with the index.php after the actual permalink path: /files/wordpress-balloons/produkt/ballon-aus-naturkautschuk/index.php

Kind regards
Mike

I don’t know about that one – that would be down to your permalink rules in both WP and NGINX. Sorry I cannot be more help, server config is not my speciality.
