I have already install the file uploader plugin. but the “upload attachment” button didn’t appear when i open my website as a guess.
i already setting the forum permission for guess in to a full access permission (i check all the “upload option” on manage permissions set for “Full Access Permission”
but when i open my website as an admin, the “upload attachment” button appeared
you can find details of the plugin here: https://simple-press.com/docum…..-uploader/
but in particular, it requires a specific permission to upload attachments is required… if you look at the permission page it will inform you that for guests (non logged in users) that uploads are not allowed… this is due to potential security issues with uploads…
so basically, only registered users with permission to upload can upload attachemnts…
i rechecked the permission page, and yes, for guest..uploading file is not allowed
thank you for you answer
