I have civicrm 4.7.31 on D7. From my old civicrm 4.1.1, I have exported the following fields in a csv file:
1) civicrm_contact (my external_identifier) in 4.7.31 2) geo_code_1 (latitude) 3) geo_code_2 (longitude)
Now, when I want to fill fields in the import contact wizard in 4.7.31, I find the latitude field, but there is no longitude field. I have tried unsuccessfully to update the geocodes using the mapping function and Google in the Mapping and Geocoding section of the system settings.
