Help! Invalid CSRF token after upgrading to v1.5.1

[btw6391]

So I finally got around to upgrading my forum for v1.4.5 to v1.5.1. I followed the steps in the documentation for upgrading (https://docs.nodebb.org/configuring/upgrade/) but when I started my forum back up, it wouldn't let me log in!

Instead, I'm taken to a page that simply says "Forbidden" while my console log says "error: /login invalid csrf token". Anyone ever experienced this? I know others had seen similar issues with an older version but was never able to find if there was a definitive solution.

Any help or suggestions is greatly appreciated!

@btw6391 Post your config.json, I think this has something to do with the URL and port. I think.

@btw6391 are you using Nginx in front? Search this forum for the error and check those posts for a tweak to Nginx.
