There is no place in the admin UI to set this limit, it is done in the web.config.
You'll need to set both maxAllowedContentLength (used by ASP.NET) and maxRequestLength (used by IIS). They should be the same value.

Thanks so much. That is what I thought, but since we are still running into problems, I wanted to confirm. Maybe it is timing out. Let me try that now. Thanks again!
This is probably going to be an easy one. So I have changed my web.config to allow bigger files for uploading. I set 100mb, yet files under 40 upload. Is there a place in the EpiServer admin UI where we can set another limit? Or perhaps some EpiServer API that lets us set this in code?
Thanks in advance.
