Hi, this is not a Servoy bug as such, but I'm mentioning it in case anyone updates an Ubuntu server to 2020.04:
The Tomcat that is part of the 2020.04 release, 9.0.31, has a serious bug disabling multipart uploads.
The first sign is that you can no longer upload war files via the Tomcat console.
The second sign is that after you upload the .war file manually, file uploads in Servoy fail.
Updating to Tomcat 9.0.37 fixes the problem.
