I have just found the solution. Some how on ubuntu 14.04, even if it is shown on the list of phpinfo, it may not be properly set. I followed the guide here and solves the problem.

Just to copy from the link just in case if the page is no longer there.

Try this:

sudo updatedb locate mcrypt.ini Should show it located at /etc/php5/mods-available

locate mcrypt.so Edit mcrypt.ini and change extension to match the path to mcrypt.so, example:

extension=/usr/lib/php5/20121212/mcrypt.so Now this:

php5enmod mcrypt - (optional since its already enabled during phpmyadmin setup) Verify that new files exists here (they should be auto created from the issue above)

ls -al /etc/php5/cli/conf.d/20-mcrypt.ini ls -al /etc/php5/apache2/conf.d/20-mcrypt.ini Otherwise do the following

Create symbol links now

ln -s /etc/php5/mods-available/mcrypt.ini /etc/php5/cli/conf.d/20-mcrypt.ini ln -s /etc/php5/mods-available/mcrypt.ini /etc/php5/apache2/conf.d/20-mcrypt.ini Restart Apacahe

service apache2 restart
