If I sign in at /forum/index.php the site rejects my password, it then redirects me to /forum/index.php?action=login2 where I am able to login with the same details and my details are accepted.
I've tried this more than once, I'm hoping it's not just me.
I've been having this happen too, but I thought it was my keychain acting funny… need to have a look at the SMF forums methinks.
Same thing here. I have the browser remember the password and I thought the browser remembered wrongly.
It works on the 2nd page.
