I am getting a constant error of

 mod_fcgid: stderr: Unknown algorithm. Expected HMAC-SHA256 

from my apache logs. I am wondering why PHP is complaining since the hash module is installed.

My PHP info:

 php -v
PHP 5.3.3-7+squeeze17 with Suhosin-Patch (cli) (built: Aug 23 2013 15:06:16)

# php -m | grep hash

@OliverSalzburg Not related to that issue! I googled that before and this is not related to Facebook SDK but another script. Plus there is no solution addressing PHP configuration in that issue –  Armand Sep 16 '13 at 19:42
    
Oh, okay. What are you running on the server? –  Oliver Salzburg Sep 16 '13 at 19:43
    
Running a script named INDEXU 7.4 . Developers are slow in responsind. –  Armand Sep 16 '13 at 19:50

You're not missing anything. Part of that application is simply causing output to stderr which is logged in the logfile. Indexu has "Facebook integration" which is probably causing this message. You can see this error message right here github.com/WarFox/socioall/blob/master/fb_data.php#L13 Indexu probably uses this project. –  Oliver Salzburg Sep 16 '13 at 20:55
