we have a lot of canned respose with pdf files. 3-4 on every canned response. When we delete 1 or 2 pdf and upload new one we get the old one back. its not possible to upload new pfd in canned respose we only get the the old ones back. we even tried to make a new response and upload files. then we got some old pdf instead of the new one.we use osticket 1.8.1.2
