Cannot download the subscriber list
-
When I try to download the subscriber list I get this error messsage:
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_DISPOSITIONI appreciate any help to resolve this.
