You might want to install the the MySQL native driver for PHP (MySQLnd) over the custom MySQL driver provided with the default EasyApache.
To enable this manually, you will need to edit the file :
/var/cpanel/easy/apache/rawopts/all_php5 and make sure the following entries are in place there :
–enable-mysqlnd
–with-mysqli=mysqlnd
Save the above file, run EasyApache from WHM and recompile as normal.
