Installing and upgrading help

First, take a deep breath!

Next, give us a little more information about what your software setup is.

Specifically, what operating system are you using?  PHP version? Moodle version?

If you are in Linux, do an ls -l /home/example/moodledata and post the output here.

You might also post some parts of your config.php

$CFG->wwwroot, $CFG->dirroot, $CFG->dataroot, and $CFG->directorypermissions would be helpful.
