File Upload Error (Undefined 500)


When i try to upload attachments tot f.i. a ticket then i get the "File Upload Error < filename> Undefined 500" error.

When i upload a small .jpg it works fine, all other filetypes result in the above error.

Tried with and without the Plugin
Tried storage on db and storage on fs
Attachments are enabled

  • OSTicket
  • max filesize is 50MB
  • no filetype restrictions
Help :(



  • Admin panel -> Settings -> Tickets -> Attachments -> Config button.

    What do you have for settings there?
  • See the screenshot.
  • What's the filename.ext of the file that your having an issue with?
  • Multiple...
    .docx .pdf .png .xls .xlsx and move...
  • Is this your own server, or are you using a hosted solution?
    Are you running anything like SELinux, mod_security, or suhosin?
    I'm wondering if file size or type is triggering a security rule and forbidding it.
  • Hi,

    It's on a hosted linux server. The file-size in php.ini is max 50MB and as far as i can see there are no file restrictions..
    I'll try to contact the provider tomorrow and let him check the security settings for the filesystem
    Thanks for your help and i will get back if i have the answers from my provider.

    Have a nice evening.

  • You as well. :)
  • Hi,

    has there been any solution? I'm running into the same issue.

    Best Regards
