@How to get full logs from FileZilla

To enable debug logging in FileZilla, you’ll need to do the following:

1. Go to Edit → Settings…
2. Scroll down to the Debug page.
3. Ensure that “Show debug menu” is enabled (it is by default).
4. Update the “Debug information in message log” and set it to “2 - Info”.
5. Click Save to update the settings.

Retry the action and gather the logs

With debug logging enabled, you should try to retry your FTP action.

You’ll see that the box at the top of the screen will fill with lots of text. This is the debug output of FileZilla.
