[xwiki-users] Include Macro not working

Good evening. I attempted to invite one of my colleagues to check out XWiki that I have setup in my organization. They got the invitation email all right, but when they clicked "Accept", they get the following error message from the Wiki: Failed to execute the [include] macro Any ideas? ________________________________ This e-mail may contain Sprint Nextel proprietary information intended for the sole use of the recipient(s).
