    Random problem with uploading documents

    Asked by BBIE on October 24, 2016 at 09:45 AM

    Since this morning we receive lots of complaints from our clients saying they cannot upload PDF files or JPG files. They get the message "You can only upload following files: "

    (there is a control on the extension in the form...). But they upload the right kind of document...

    We could not reproduce this here this morning, but there are more and more complaints. And since half an hour, we sometimes get the same message (and sometimes not...). It is completely random. Also clients who could not upload documents this morning called us after a while they finally succeeded. But some time later, it stops working again.

    This is a very annoying situation. Do you have an idea of where it can come from?


    Thanks in advance
