Testing Plugins for Multisite

I’ve used several popular plugins on my multisite without problems.

The only issue I had was when I found that a plugin wasn’t working on a sub-site like I thought it should. Turns out that was my fault – the plugin wasn’t activated/enabled on that sub-site. Doh!

But it all depends on how the plugin is written, and how it is expected to work on a site. Most plugins, as Tom J Nowell stated/implied, should work just fine on multisite and sub-sites.
