191 ERROR yellow GPS messages appearing in the chat...

For those wondering about some yellow GPS messages appearing in the chat like:

Example from Facebook page

If setting up the GPS messages, either use the message provided by the DPRS button as it is, or edit it manually and REMOVE the initial 2 character group and the checksum (the info after, and including the * character). Otherwise, it will trigger a checksum error at the receivers leading to the yellow lines... So it is something like "Marius, KN05or" or DPRS "LY KN05OR*49" as the icon and checksum is added by the code behind the DPRS button.

The same issue happens any time that you change your callsign (e.g. you change from IZ2LXI to IZ2LXI/P) without then updating the checksum...

Errors will appear like these:

Gps : Failed to parse DPRS comment: BN *5C
Gps : CHECKSUM(IZ2LXI-W): 38 != 92
Gps : Checksum : *5C
Gps : _checksum: *26
Gps : astidx : 4

How to fix this?

Solution is simple: just go to default GPRS comment:

Preferences-> gps config - > (press DPRS button)

Also, the same happens if you configured DAPRS in the QST section. You must change it there, also, or it will give an error.
