Unable to upload .zip fle

I am trying to upload Yoast.zip SEO (5.25M) but only get this message :”The uploaded file exceeds the upload_max_filesize directive in php.ini”.

I have installed this php.ini in the root but it still will not upload. Have been trying for about three hours.

upload_max_filesize = 64M
post_max_size = 64M
memory_limit = 400M
file_uploads = On
max_execution_time = 180

Any suggestions, please?
