Click [Submit]

You should now be on the main Settings screen again, click 'Obtain Transaction Key' under the Security group. Enter the appropriate secret information and a new key will be generated for you.

Note:

If you already know your transaction key you dont need to generate a new one

You will now need to edit includes/functions_subscriptions.php to tell vBulletin the transaction key for your account, this is stored in a file rather than the Settings in the Admin Control Panel for security reasons.

To edit the functions_subscriptions.php file, you will need to open the file in a text editor such as Windows® WordPad. (Note that we do not recommend that you use Windows® Notepad to edit functions_subscriptions.php, as Notepad has problems displaying the line breaks in some file types.)

The top of the file will contain
