Cannot upload macro excel file

I have a problem with uploading macro (xlsm) files in a SharePoint Foundation 2013 Site collection. Strange is that on other SharePoint site collections which are on separate server farms, it works normally. Could the problem be that the version of our SharePoint is too old which is 15.0.4420.1017 and the other one has a newer version.This type of file is not blocked in the central administration so I'm not sure what the problem is.

Thanks and kind regards
