I am getting this error when trying to upload or attach an image to a post - Oops! We ran into some problems. The uploaded file was not an image as expected.

What is the format of the image you're trying to upload?

This typically happens if the file has an extension which is different to the actual extension.

Is it for all images?

Can you upload them here?
