This is my first WordPress site. I've installed it on my Linux Ubuntu 16.04 remote server (which is in my house). I've got a LEMP stack installed on this server. When I try to upload images to my WordPress site, I get an error that says:
The uploaded file exceeds the upload_max_filesize directive in php.ini.
I changed every php.ini file I could find to have upload_max_filesize = 64M. In fact, the upload page for my WordPress site specifically says "Maximum upload file size: 64 MB." So, I know my changes have been implemented. However, no images will upload. Even images < 2 MB.
