We experience error when uploading file on osticket/upload/tickets.php site by user.
Error says: File Upload Error: #filename# udefined500.
Previously on 1.15 we did not experience the issue, however we updated to 1.16 recently.
Can someone please help us how to troubleshoot or solve further?

Many thanks!

      Inspect the page, go to the network tab, make the request, and look at the Response for the request in the Network tab.

      Cheers.

              Response: File is too large
              It is very interesting as we did not had this issue before. I am testing with a 1.7MB file while the settings is 32MB file limit for Attachment on Tickets and also on Attachments Storage and Settings.
              Any idea what could be the cause or how to resolve it?
              Thank you

                  There are older threads that explains the changes needed in Apache and potentially PHP-fpm if you’re running it.

                  Cheers.

                    Hi @KevinTheJedi
                    Is there any chance you could be a bit more specific? I tried to read the related topics, but could not find anything that might work or we have not yet tried.
                    Thanks,
                    Adam

                      You can Google this to find the answers but:

                      • upload_max_filesize
                      • memory_limit
                      • post_max_size

                      Cheers.

                        Hi @KevinTheJedi We tried all, but seems to be something else..
                        We traced it further and in filedrop.field.js?e148727 we can see that this part returns the server response improperly.

                        We could not find any reason why this is not working or how to resolve. Any chance that you could help us?

                        Thanks

                        8 days later

                        Did you check the settings in PHP that Kevin mentioned?

                        upload_max_filesize
                        memory_limit
                        post_max_size

                        Did you increase the sizes of those attributes, and then restart the webserver service?

                          Hi ntozier ,
                          Thank you for reaching out to us. Unfortunately issue remained the same. We did the checks & changes suggested by Kevin, but nothing has changed.
                          Also, we upgraded last Thursday to 1.17, but no change on this error.
                          Do you have any idea or suggestion how to troubleshoot further?

                          Many thanks,
                          Adam
