I am unable to open the wand inv on both the test server and my own server. Any advice?

Test server, like mine.elmakers.com ? You are pressing the Q button, right?

If you mean your own servers and you have custom wand configs, there are some properties you may need to add, see MIGRATION.md for details.

Specifically here, if it's a config issue:

Thanks! it works now
