Nginx returns 413 – Request Entity Too Large when attempting to upload a file larger than 2 MB
In /etc/nginx/nginx.conf , add this line or change the existing line to: client_max_body_size 256M;
WordPress reports The uploaded file exceeds the upload_max_filesize directive in php.ini.
In /etc/opt/rh/rh-php70/php.ini change upload_max_filesize from 2M to a larger number, like 128M
Some other things to consider in php.ini:
max_execution_time = 60
memory_limit = 256M
post_max_size = 128M
