When trying to download certain files from the website using Google's Chrome browser, you may receive a "Duplicate headers received from server" error like the one shown in the image below:
This error is caused by a comma in the filename of the file you are trying to download. Some of the files that Back Office generates for users to download use the company name as part of the filename. If the company name contains commas and if the code to produce a particular file doesn't do anything with the commas when using it as the filename, users will get the error above when trying to download it.
This issue was noticed when downloading the PDF version of the Company Questionnaire from Contact Management. It has since been fixed in this particular instance by removing the commas from the filename, but there may be other places where this has not been dealt with.
