HI Guillermo
Thanks a lot, I really appreciate your help. You are totally right, the PHP version was totally wrong. The PHP version needed should be PHP 5.3. Another thing is the MYSQL version, in a web shared hosting at GoDADDY.com they provide an older version 5.0.X , so there is no way that you can install the latest version of Moodle (2.3). You have no idea how many tickets I post to godaddy, once to change the PHP version, other tu upgrade the MYSQL, etcetera. At the end I had to install Moodle 2.2 so in that way it is compatible with MYSQL 5.0.x, and I finally was able to install Moodle at my hosting.
Thanks a lot, for taking time to answer this question
