Nginx Bad Gateway Errors

[Bharat]

Hello Peps ,

i installed nginx as reserve proxy in Cpanel by some auto installer , all goes super fine , and now the sites are working faster then before.

But the problem is really wired , i am getting Nginx 502 Bad Gateway errors while logging into my site , while editing any posts , while creating any posts , etc . Except then this the Front end interface is super fine and clean with no errors .

Please suggest me the ways to solve them .

502 errors are usually caused when PHP freaks out for some reason. The first thing you should do is check all of your logfiles. That includes system stuff in /var/log/ and the nginx logs.

If you haven't made any recent changes and the problem just started happening for no apparent reason, PHP may be running out of memory. I know when it happens as an Apache module it gives a blank screen--wouldn't be surprised if a 502 error happened under nginx and the FastCGI interface. That's easy to fix by putting ini_set('memory_limit', '256M') into your index.php and see if that fixes the problem.
