uploading files to Safari
I've been having issues with uploading documents to websites using safari (version 7.1.2) that say they only allow certain file types. I upload one of the file types specified, but than I get an error message saying that the file format is not allowed (or something like that) even though it is. For example, the site could say it allows .doc, .docx, .pdf, .txt or .rtf files, and I go and try the same file in .doc, .docx and pdf, and all 3 times it tells me the format is not allowed. There was one site that also allowed .jpeg files, and that format it did accept.
I also went back to try the same files on the same websites using my old Windows PC, and was able to upload them fine on there.
