osTicket v1.10 (stable) and Maintenance Release v1.9.15 are now available! Go get it now

File Upload Error: undefined400 when attaching file only while creating a new ticket

osTicket Versionv1.9.9-1-gbe2f138 (be2f138)
Web Server Softwarenginx/1.0.15
MySQL Version5.5.44
PHP Version5.4.23
Note that attaching tickets to existing tickets works properly and tThis functionality was working properly prior to some customization work.  

While in the process creating a new ticket, the process fails after the progress bar for loading the file gets all the way to the far right.


  • nginx is not a supported webserver.  There are a number of configuration changes required to make it work.  There are several very long threads on github about getting it to work.  I would suggest that you go read them.
