I haven’t seen this one before Tim. Are you using DiscourseConnect? Just testing it now in a single site environment the user switching plugin is working as expected. I’ll test it in a mutlisite tomorrow.
In the meantime, can you share your:
- WP version number
- WP Discourse version number
- User Switching plugin version number
- PHP Version number
You can find all of these in the WP Discourse Logs page by clicking “View Meta”. If you could possibly share that entire file with me (via PM) that would help, thanks.
