Can't upload png media files

We have a v6.1.6 site which has been running for a while now. Just recently our clients have advised us that they can no longer upload png files - Umbraco returns Page Not Found when they try to save the new media type.

We are using the "Upload field" property editor for the image upload.

This is the error from the log file:

2018-03-01 12:39:06,359 [21] ERROR Umbraco.Core.UmbracoApplicationBase - [Thread 29] An unhandled exception occurred

Any ideas what could be causing the problem?

I can load png files on my local version of the site but both the test and production sites error...

That looks like the kind of error you get when you run out of disk space?!

Almost certainly not this but what's the setting in the \config\UmbracoSettings.config for disallowedUploadFiles
```
<disallowedUploadFiles>ashx,aspx,ascx,config,cshtml,vbhtml,asmx,air,axd,swf,xml,xhtml,html,htm,svg,php,htaccess</disallowedUploadFiles>
```

<disallowedUploadFiles>ashx,aspx,ascx,config,cshtml,vbhtml,asmx,air,axd</disallowedUploadFiles>

also

  <imageFileTypes>jpeg,jpg,gif,bmp,png,tiff,tif</imageFileTypes>

Hi Lesley

Just a random idea, but maybe worth a shot.

Are you able to open the file in an image editing program, save it as a different filename and try uploading the new file ?

Cheers

Nigel
