Error following plugin installation

Hello, I hope that you are all good!
I have tried to install the following plugin on my WP Multisite (latest version). This is the error message I get:

Warning: require_once(../wp-load.php) [function.require-once]: failed to open stream: No such file or directory in /home/public_html/wp-content/plugins/recent-global-posts-feed/recent-global-posts-feed.php on line 28

Please advise. Thank you.
