I'm getting an error on Image Upload and Asset Editing on an existing site. I'm getting the
Upload failed. The error message was: “The file “.../storage/runtime/temp/...” does not appear to be an image.” error that's been discussed previously here. Imagick version 3.4.3 (ImageMagick 6.7.8-9) is installed. Switching the file, the format, or reuploading a previously uploaded image also does not work. Editing old assets w/n Craft yields a generic image icon.
No recent changes to the server that Im aware of. PHP 7.0.33. Craft Pro 3.3.1 ('Im stuck in the upgrade process -- see my other question previously).
