Plugin Installation on MultiSite

Good day to all.

I am using a WP MultiSite network and today I tried to install a plugin from the SuperAdmin panel, but received an error – “Unable to locate WordPress Content directory (wp-content).” – but when I visit it via FTP, I can easily find it. Then, if I upload the plugin via FTP I can go back and activate it in the dashboard.

Is this normal activity for a WP MultiSite network or is this something that I’ve created by doing something wrong?

Thanks in advance for any help/suggestions.
