You need to update your
forum profile with the output of the following command (do not post the information in this thread):
Which browser are you using? Does this happen on all accounts or just some? Has it always happened or just started? Do you have any add-ons or extensions in the browser that may be causing a problem (if it's FF you can create an empty profile to check)? What do you mean by 'the attachment cannot be seen', what exactly happens? Are there any errors in the
log files when you try to view an attachment?
