Feedback 502 Bad Gateway error

Not sure if this will help you but friend of mine had similar problem on Vbulletin forum and he fixed it like this:

in includes/functions_login.php
Line 376:

// vbsetcookie will add the cookie prefix
vbsetcookie($key, '', 1);

PHP:

add a space between the quotes so it will look like this:

// vbsetcookie will add the cookie prefix
vbsetcookie($key, ' ', 1);

PHP:

 

Thanks for showing error I was also getting it from Last 3 days at every login. I am using Win 7 ultimate 64bit, Chrome v25 and every time I close browser my cookies and Cache is cleared that is my settings. Also tired by changing IP. I thought it was only me but now it's just not me.

 

I've had this about thirty times myself. I was already logged in. Also, when making replies, they have been timing out to bad gateway.
