I get the error "can't parse json response from backend" when trying to upload some types of pptx files with images on the slides. I am running Foswiki 2.1.2 with natskin and have applied all the recent extension updates. Our foswiki is running on Ubuntu 16.04 LTS.

I have attached a screen shot of the error message and an example pptx document that is causing the error.

It was a nginx configuration issue that prevented large files from being uploaded, not a problem with foswiki. I followed the instructions for nginx configuration on the foswiki site, but now I also added the line client_max_body_size 200M; into the server block sections of the nginx configuration file under sites-available. I added my nginx config file in case others have the same issue.

I've added the client_max_body_size setting to our example Nginx configuration shipped with FastCGIContrib. Setting this to no-action.
