FileAttachementError

If you don’t have $MaxAttachmentSize set in RT_SiteConfig.pm and neither $TruncateLongAttachments nor $DropLongAttachments is set to anything other than undef, then there shouldn’t be a size constraint in RT.

What web server are you using?

We are using Nginx and we had to set the client_max_body_size on the location block of our web server configuration.

We set ours to 50M:

client_max_body_size 50M;

If you are using Apache there are plenty of posts troubleshooting similar issues. I have one in my notes.

These are the links from my notes:

Default nginx client_max_body_size

RT5.0.0 Attachments failing to appear

Found the problem. Since Apache v2.3.6, FcgidMaxRequestLen is defaulted to 131072 bytes, prior to that it defaulted to 1GB. Any attempt to send an HTTP request bigger than 131072 bytes causes a 500 Internal Server Error. apache.conf doesn’t show any entry for FcgidMaxRequestLen, so it’s deault value is hidden. I had to add one. I’ve set it to 25MB for now which is the same as the max email attachment size.
