When attempting to open a spreadsheet I get an error message “jackrabbit webdav server requires username password” referring to “us.pioneerinvestments.com”. I have never heard of that organization and there is no reference to it in my spreadsheet. Attempting to click though with the username and password blank or with “admin, admin” does not work. The only way out is to use task manager to end task. This is a spreadsheet that was working fine for months. I am running under windows 10 if that is significant.
Any suggestions?
