I'm working on an article and cannot upload any images to it. My images are all .png (though I changed one to .jpg just to try it and it still didn't work). The biggest image is 23kb and 500 px wide so they should all meet the requirements.
When I click the Upload button I get this:
Unexpected error during upload. One or more files may not have been uploaded.
I thought maybe my work was blocking access somehow, but I was able to upload a profile picture to my account.
