Upgrading from version 1.4.5 to 1.11.2 / Unable to Save General Settings

[rod]

I have upgraded my dev forum from NodeBB v 1.4.5 to 1.11.2 and have run into a few issues. The first is that I am unable to save changes to the Settings > General tab. When I click the save icon I get the following error:

"Changes Not Saved

NodeBB encountered a problem
saving your changes. (Input file is
missing)"

Which input file may be missing?

Thanks.

I think it might be the site logo, can you try re-uploading it, saving, and seeing if the error continues?

Thanks @julian, that solved that issue.

Additional details. The problem may be the way that I have my S3 content bucket locked down such that my dev forum cannot access the files (different subdomain).
