Can’t login

I’ve used the old, standalone GlotPress so I’m familiar with the relationship between the GP users and WP users. However, after installing the plugin and going to my projects page (https://chrisreynolds.io/glotpress/projects/) I have a Login button and no ability to create new projects. The login button links to the login page on my site, but when I click it, I’m not redirected (presumably because I’m already logged in, but GP doesn’t see that).

I don’t think this is a cookie thing because the same thing happens when I try in an incognito window, the only difference is I’m redirected to the login page and log in. After logging in, I’m still unable to add projects.

I’ve checked the gp_permissions table and my admin user id is indeed in the table.

This is on a WordPress multisite. I’ve tried network activating the plugin and have verified the gp_permissions on both the main WP site on the network as well as the subsite in case the issue was one of not being able to access the wp_users table outside of the subsite, but I get the same issue on the main site.

I’m happy to create users manually if that’s still a thing. I don’t need to manage users via WP, I just need to be able to manage translations.
