Why do I have an error when uploading a photo into a discussion reply? I have been trying for 2 days to upload a photo (both in jpeg and png format) into a discussion reply on two different computers and I keep receiving the same error.  I have uploaded to multiple discussion boards before and had no problems until now.346694_Screen Shot 2020-05-04 at 10.43.54 AM.png
