My nginx error are:
2014/06/27 15:08:15 [error] 4922#0: *886 FastCGI sent in stderr: "PHP message: phpmyadmin: Failed to load /var/lib/phpmyadmin/blowfish_secret.inc.php Check group www-data has read access and open_basedir restrictions.

PHP message: phpmyadmin: Failed to load /var/lib/phpmyadmin/config.inc.php Check group www-data has read access and open_basedir restrictions" while reading response header from upstream, client: 1***, server: _, request: "GET /phpmyadmin/js/messages.php?lang=en&db=&token=**** HTTP/1.1", upstream: "fastcgi://unix:/var/lib/php5-fpm/ispconfig.sock:", host: "****:8080", referrer: "https://****:8080/phpmyadmin/chk_rel.php?db=&table=&server=1&target=&token=****"
I give them permissions with this cmd for all 3 files:
chgrp www-data /var/lib/phpmyadmin/blowfish_secret.inc.php
chmod 644 /var/lib/phpmyadmin/blowfish_secret.inc.php
How to fix the open_basedir restrictions?
I checked Google but didn't find anything. Please give me some help or tips how to fix it. Thank you!

Here's my configuration:
drwxr-xr-x 3 root root 4096 feb 14 10:05 phpmyadmin/
that's for folder. And for those two files:
-rw-r----- 1 root www-data 60 feb 14 10:05 blowfish_secret.inc.php
-rw-r----- 1 root www-data 0 feb 14 10:05 config.inc.php
Hope this will help. Also check for php5-mcrypt extension. If it's not working properly, use
sudo php5enmod mcrypt
to install it, and then just restart ngnix. here are commands:
chmod 755 /var/lib/phpmyadmin
chmod 664 /var/lib/blowfish_secret.inc.php
chmod 664 /var/lib/config.inc.php
those commands should work. :)
