Max Upload File Size for MultiSite
Got problem when my media upload is limited to 1MB only. First things first is to make sure that php.ini in our server set the upload_max_size with the size we like to allow our user to upload in our website.
upload_max_filesize = 64M
post_max_size = 64M
max_execution_time = 300
And if our server settings are ready, we need to set the file size upload on our multisite Settings to the size we intent.
