webmail error 500 + cpsrvd.pl

My clients is having problem accessing the webmail. I've check the scripalias directive and it seems to perfect. I doubt its an apache problem as I'm accessing it through port 2096. here's the cpanel error_log

Code:

Content-type: text/html

Internal Error: "GET /3rdparty/squirrelmail/index.php HTTP/1.1" Unable to open engine binary (php) at cpsrvd.pl line 4482
        main::phpHandler() called at cpsrvd.pl line 3383
        main::dodoc_webmaild() called at cpsrvd.pl line 635
        main::dodoc() called at cpsrvd.pl line 541

i tried upcp --force, fixeverything, restart cpanel. none works for me

 

Fixed this problem by copying the whole squirrelmail and horde directory from my other server into the server with problem. It turns out that both folder didnt exist.

Code:

/usr/local/cpanel/3rdparty/squirrelmail
/usr/local/cpanel/base/horde
