It is a bug in the installer. If you have only one database type available, it might not correctly be selected. Around line 1070 of install.php as distributed in FUDforum_2-7-7.tar.gz, you can add one line to sort this out.

The reason is the use of current() to choose the database type. The internal pointer into the array might not point to anything useful once elements of the array have been removed. Resetting the internal pointer to the first element of the array ensures that if anything is left in the array, the pointer will point to something valid.

                        foreach ($types as $k => $v) {
                                if (!$module_status[$k]) {
                                        unset($types[$k]);
                                }
                        }

                        reset($types);   // <<<---- Add this line

                        if (count($types) > 1) {
                                draw_row_sel('Database Type','DBTYPE', implode("\n", $types), implode("\n", array_keys($types)), '', (isset($_POST['DBTYPE']) ? $_POST['DBTYPE'] : 'mysql'));
                        } else {
                                echo '<tr bgcolor="#bff8ff"><td valign="top"><b>Database Type</b></td><td><input type="hidden" name="DBTYPE" value="'.key($types).'">Using '.current($types).'</td></tr>';
                        }
