Firstly, you should upgrade to 1.7.5 asap as there a couple of security issues that have been fixed recently.

For your specific error, that comes from the Single Sign On feature. Presumably you have edited the 'qa_get_mysql_user_column_type' function in 'qa-external/qa-external-users.php' but you must return a valid type from that function. See the comment above it for the possible values you can use. For example

return 'INT UNSIGNED';

If you are not using SSO then delete or rename the 'qa-external' folder in your installation.
