Why is it that file uploading in wordpress doesn't work when I run PHP-FPM through mod-proxy-fcgi with mod_http2? As soon as I disable http2, it all works swimmingly and I can upload files with no issues.
I'm using the same php.ini settings (max post size and max upload size) for both PHP-FPM and the apache2 mod, but for some reason when I try to upload a file when I run through PHP-FPM, the file stops uploadi...
UPDATE: I resolved the issue by disabling http2. It looks like both mod-proxy and mod-fastcgi don't play very well with http2.
