Hi Jennifer, then we better get started. When you initially logged in, did you give yourself an identity? You should have been prompted for an id and a password that contains no less than 8 characters, with one a capital letter, one number and one non-aplhanumeric character. This, for me, is a complex annoyance that really needs to be reviewed - but all bow to the Gods of Security... That should also have been where you entered your id. If you cannot find it then you are going to have to cheat. There is a couple of possibilities, but they are anoyances themselves - and I have just tried them in 2.1, they have worked in 1.9 and earlier versions, and it works in this version as well.
What you need to look for is:
1. the httpd.conf file in th eXampp folder somewhere - open it and look for "DocumentRoot" Write down the value you find there it may be something like "C:/Xampp/server/Moodle"
2. In the Moodle folder the config.php file uses some values that look like:
$cfg->dbname = 'moodle'; // your database name inside MySQL
$cfg->dbuser = 'root'; //a default identity for database access could be anything
$cfg->dbpass = 'yourpasswordhere'; //your password, not mine could be harrypotter or jtkirk for all I know.
Write these values down as well.
3. Go to download PHPMyAdmin and install that. It is a simpler process than most other PHP Apps, just unzip to the DocumentRoot folder, run it by opening it in your browser and it should installand work with a minimum of fuss. It will ask for an identity and a password to open your databases with, so give it the values of dbuser and dbpass. When it is installed, that should allow you access to the Moodle database so open it by clicking on the Moodle name in the left hand collumn.
4. Scroll down to the user table. The first entry should have a user name of Guest. Following the user field, there should be a set of numbers under the password collumn.
5. Copy those numbers, all of them.
6. Look for your identity, which may be the next one down and click on Inline Edit. Scroll over to password, and paste over the top of the password there. Click on "Save" in the same row and that should return to the earlier page with a new password in your identity.
7. Open your Moodle and put in your identiry and the password of guest. You should now have access.
I know this seems complicated, but it is not really, just annoyingly fiddly. Slow and steady here, and one step at a time. Someone else may have a better idea but this is the only one that seems to work in this circumstance. You may also remember the password when you see what identity you used, in which case try it. If it works then keep going, if not then come back to this. Good luck...
