Multisite network issue again

Tried this on multsite and it broke the network admin pages with the same error described here: https://wordpress.org/support/topic/php-fatal-error-on-multisite-network-admin-screen/ I tried the fix lited in the comments, but while it worked it triggered a whole load of warnings about php that will be deprecated in future versions. This is a heads up for when you get to it as I’ll be following your advice and using a different plugin. But lots of people still use multisite. I understand if you don’t want to support that, but you should at least sat it’s not suitable for multisite. I also got errors in trying to use your admin page and post notes on multisite.
