# Troubleshooting

> Fixes for settings that won't save, payment links in PDFs, and "Oops, something went wrong" at checkout.

## Your settings won't save

Check that every option you've ticked has its details filled in:

- If **Email when payment received** is ticked, enter an email address.
- If **Add payments to QuickBooks** is ticked, choose the account to record payments against.

## The payment link in a PDF invoice isn't clickable

Whether a link in a PDF opens a browser depends on the program the PDF is opened in, which Shuttle can't control. PDF readers such as Adobe Acrobat Reader usually make the link clickable.

If you're worried about this, add a line above the link in your [invoice template](/merchants/quickbooks/invoice-links/), such as "Copy this link into your web browser to pay online."

## "Oops, something went wrong" at checkout

This usually means QuickBooks has disconnected from the Shuttle app, for example because the connection hasn't been used for a long time, or someone disconnected the app in QuickBooks. To reconnect:

1. Log in to the Shuttle app.
2. Select **View Configuration**, then **Accounts** > **QuickBooks**.
3. Select **Reconnect**.
