I've set up a colleague to use the announce list feature to send our church newsletter. She's done it successfully for weeks. Today, she's getting the error "Please remove any non-standard characters" when she tries to send it. She's sent me the html for the newsletter. I've replicated the problem. I can't image what non-standard characters it's finding. Looks like straight ascii text to me.
Does anyone have a suggestion about how to address this?
