@patrick-anderson It should be on the network tab of your browsers console. Try uploading something while the network tab is open and it should show you the failing request. Then you can check what the server has returned in the same window.
Image size & uploads
On NodeBB 0.9, with the Persona theme (and using the nodebb-plugin-s3-uploads & nodebb-plugin-composer-redactor), I find that images dragged and dropped into the compose post panel end up being displayed without being resized based on page width and end up being cropped. This is obvious on a mobile device but also happens on desktops with large images.
Is this a feature, an improvement or a bug?
