Session error and vqmod is not working

hi

pdo_extension error is resolved by server guys still vqmod is not working.

This is reply by server guys::
------------------------------------------------------------------------

The PDO extensions were being called separately within the PHP configuration 
which was causing the errors:

root@server1 [/home/foxyeve]# grep -i pdo /home/foxyeve/public_html/php.ini
extension=pdo.so
extension=pdo_sqlite.so
extension=pdo_mysql.so

As the extensions are compiled into the binary and not separate, I backed up 
this file and commented those lines out:

root@server1 [/home/foxyeve]# php -m | grep -i 'pdo'
PDO
pdo_mysql
pdo_sqlite

root@server1 [/home/foxyeve/public_html]# cp -pv php.ini{,.$(date +%F).bak}
`php.ini' -> `php.ini.2014-07-28.bak'

I then monitored the PHP error_log once more while visiting the site and the 
errors are no longer showing at this time.

-----------------------------------------------------------------------

And I try to install new version of vqmod it shows me following error::
-----------------------------------------------------------------------
Warning: session_start(): Cannot send session cache limiter - headers already 
sent (output started at /home/foxyeve/public_html/vqmod/pathReplaces.php:1) in 
/home/foxyeve/public_html/system/library/session.php on line 12 
-----------------------------------------------------------------------

and when I see http://www.foxyeve.com/vqmod/install/ page it shows The page you 
requested cannot be found.

Please give some solution. I am using 1.5.6.4 version of opencart & Linux 
server.

Thanks & Regards
Nitasha
