SOLVED: Http 500 error caused by .htaccess in CMS Ubuntu

A recent move of my server from a public server to a self hosted server in Ubuntu had turned into a problem solving challenge.  I had build a new Ubuntu server with webmin as a hosting manager.  A current live version of Joomla was moved over to this server, and all of a sudden the SEF stopped working.  I am currently a user of SH404 with JoomFish, and everything worked before.  Now I got 500 error even in the admin screen.  I made sure the naming convention is right, .htaccess was typed correctly.  The main error was that by default apache does not turn on mod_rewrite, to do that in a Ubuntu or Redhat server all you have to do is type

sudo a2enmod rewrite

 

and restart the apache server by typing 

sudo /etc/init.d/apache2 restart

This should fix all those errors when migration a CMS to a new Ubuntu server.

Enjoy
