ERROR when Import/Export users from/to CSV file with extra fields

[raoni]

Hi, When I try to EXPORT User I always receive an error message from my browser:

Duplicate headers received from server

The response from the server contained duplicate headers. This problem is generally the result of a misconfigured website or proxy. Only the website or proxy administrator can fix this issue.
Error code: ERR_RESPONSE_HEADERS_MULTIPLE_CONTENT_DISPOSITION

Could you help with that, please?

Thanks

Hello, It might be some date coming as header before UMP trigger header to create CSV file, please try with temporarily disable other plugin to check if some other plugin trigger header too. Thanks.
