Unknown error when trying to restore settings

[Stefal]

Describe the bug
When I try to restore a previous settings file, it doesn't work, and display "Unknown Error"

To Reproduce
Steps to reproduce the behavior:

1. Go to 'Restore'
2. Select the file to restore, with an old setting in it (local_ntrip, which is not used anymore)
3. Clic on 'Restore Settings'
4. See error

Software/Hardware (please complete the following information):

• RTKBase release number 2.4.1

Additional context
The problem is the old setting in the conf file:

[local_ntrip]
local_ntripc_receiver_options='-TADJ=1'

If you delete this section, you can restore the config file successfuly.
