To go through the basics, there are a few things I'd like you to confirm:
- Has the page completely finished loading?
- Have you tried removing all cookies that belong to the chroniclesofelyria.com domain?
If you've done that, could you perhaps check the following, since I know you know how most of these tools work, I'll omit the in-depth explanation;
- Check the developer console for any errors (you can ignore all react & 404 errors).
- Check the network tab of those developer consoles to see if the login request is being sent out, and if it returns a non-200 status code.
If you need any more assistance in this feel free to let me know.
