invalid CSRF token during registration

[crazycells]

We got some complaints from new users that right after registration, they get an error and see a blank "forbidden" page with a link like this:

register/complete/?_csrf=XXXXXX

however when one person deleted the part ?_csrf=XXXXXX... and click the link, he was able to log in... After looking at the logs, I can see these mistakes happening frequently...

we are currently using 1.18.6, should we upgrade to 1.19 to eliminate these errors?

[crazycells]

this is our nginx config file:

this is our nodebb config file:

[crazycells]

additionally, the main site is WordPress, and NodeBB is installed at /forum

I suggest updating to 1.19.0 and applying this change as well https://github.com/NodeBB/NodeBB/commit/e9ee843b274b1e1f38b992650f3f74f940a20a49.

After that users might have to clear their cookies and refresh their browsers. Let us know if they still experience csrf errors after those changes.
