The fix: I did not realize it but there is an upload limit setting in the back end of WordPress when you are running on a WP multisite that sets the media library upload limit very low. Liquid went into the back end and PRESTO! I shared the screenshot below. Happy site building 🙂
If that does not work I just love this free plugin. It does require you to have FTP access to your website but it has worked every time for me. It’s called “add to server”. Get add to server here. You will need to create a file in your home directory and put the large file in that. Then, after you install and activate the plugin, it allows you to upload files to media library no matter the size!
