Regarding the live vs staging sites, does the license need to be active for the plugin itself to be activated? Or is that just needed to enable the functionality or at least the ability to accept donations?
If it’s not needed for the plugin to be active in the context of the WordPress install, then it shouldn’t be a blocking issue.
Sounds like you’re willing to allow me in to the staging site. I recommend creating a temp admin user for myself to use, instead of providing the user/password for an existing one on the site. Please use michael @ webdevstudios.com for an email address there. Also, as much as it feels like I’m asking too much, some FTP access to the staging site would be beneficial as well, since I know the editors for plugins doesn’t go too far, in terms of nested folders, and it’s possible that the files I’d need to look at are more nested than I’d be able to access. For that, if you’re willing, just email me those directly.
Thanks all for sticking with us thus far.
