I just created a WordPress installation using the built in addon tool.
One bug.
When creating the database and user, the script seems to ignore the entered database name, and uses username for both database and username.
Example
I entered the below:
db = abc
user = xyz
Generated username and db name:
db = xyz
user = abc
Just thought you should no.
Otherwise you will get DB Connection error from wordpress unless you change the wp-config.php to match what you actually created. Or name the two the same to begin with.
