Troubleshooting

Installing and opening

Windows says it protected your PC. Choose More info, then Run anyway. This shows for new apps until Windows has seen them on enough computers.
The app opens on the database screen every time. Choose a database from the recent list: it opens in one click. On a server, type the password again; it is never stored.

"PostgreSQL credentials are required again after restart". For your safety the password is not kept. Choose the server connection from the recent list and type the password again.
"Connection failed". Check the host, port, database name, user and password, then use Test connection. Make sure the server accepts connections from your computer and that your network can reach it.
"Database is locked". Another program, or a second window of the app, has the same file open. Close it and try again. A database file shared over a network folder can lock too: share a PostgreSQL server instead. See Your data.
"Database file does not exist". The file was moved, renamed or is on a drive that is not connected. Open it again from where it is now, or restore it from a backup.

A total looks wrong. Check whether each line's tax is added or included, and whether a discount is on a line or on the whole invoice. See Taxes and discounts.
An invoice says "Overpaid". More was recorded than its total, often a payment typed twice. Open the invoice and remove or correct the payment.
The number is not the one I expected. Numbers count up per client by default. Choose another series in Numbering.
An old invoice still shows my old address. Invoices keep what they were saved with. Open it, choose the business or client again, and save.
"File is too large". Logos, signatures and attachments can be up to 2 MB each. Make the picture smaller and try again.

The export says something is required. The message names the missing field: usually a country code, VAT code, Peppol id, buyer reference or due date, on your business or on the client. Fill it in and export again. See E-invoices.
The XML does not match what I see. Save the invoice first, then export.

"No printer is available". Connect a printer, or set one up in your system's settings. To keep a copy instead, choose Export PDF, or save the receipt as a PDF from the print dialog.

The dashboard says documents are left out because a currency has no rate. Add the rate of that currency in Currencies, or use the link on the dashboard. See Currencies and rates.
A report prints fewer rows than it has. Print shows the rows on screen. Export to Excel saves every row.

"Failed to process the following rows". The message lists the rows that could not be read. Compare them with the template columns, fix them, and import again. See Working with lists.
Importing a backup replaced my data. Import restores a backup in place of what the database holds. To keep both, create a new database first and import into it.
