Both on our demo forum and in
File Bank here PDfs are allowed to upload; but you always must follow file upload rules and disclaimer which reports the maximum allowed size. Currently, on demo forums it is allowed to upload not more than 100 Kb and here it is up to 1 Mb.
It is also important to check the file type which is reported in
your exact browser. Different browsers can interpret the same file type differently. It seems '
application/pdf' type which is currently set by default in this add-on, works only in Internet Explorer/Opera... in Mozilla, it is interpreted as '
application/octet' for some reason (but this is obviously wrong). So setting this type and the proper file size you can achieve that PDFs will be uploaded (like now I've set it on
miniBB demo forums); however please note this filetype maybe used also for other applications, and so files of other extensions probably could be upload as well.
Refer to
how_to_add_uknown_file_type.txt file supplied with this add-on for getting the idea of how to determine the file type you upload.
