[SOLVED] Roundcube Internal Error 500

[DRS]

Hello,

I upgraded to the new VestaCP and roundcube is dead -> mydomain.com/webmail -> Internal Server Error 500.

Before upgrading work properly. Could someone help me?

Software: Debian Wheezy, NGINX 1.9.6, MariaDB 10.0, VestaCP 0.9.8-15, Apache 2.2.22, PHP 5.6.15

Thanks.

SOLVED!

Looking at the error logs found:

[Thu Nov 12 12:33:12 2015] [error] [client YourIP] PHP Fatal error: Call to undefined function: MDB2_Driver_mysql::pushErrorHandling(). in /usr/share/php/MDB2.php on line 1950

The problem is that lack a module, therefore, install it: (Debian/Ubuntu)

1º) Install MySQL package for MDB2:

apt-get install php-mdb2-driver-mysql

2º) Install PHP-Pear:

apt-get install php-pear

3º) Install MDB2 Library:

pear install MDB2

4º) Install MDB2 MySQL Driver:

pear install MDB2_Driver_Mysql

Ready! No need to restart.
