That looks like a real bug in XWiki. The problem comes from the quotes in the user's name: Henri-Robert "test" Sully
A quick fix is to remove the "test" part from the name, since I doubt real users will actually have quotes in their names. But ' is quite common in names like O'Brian, and that will still break the share page feature. There seem to be two XWiki bugs involved: - The username is HTML-escaped, but in this case it shouldn't be - The Q encoding is wrong, it doesn't escape & and # On 01/30/2017 03:28 PM, Sully, Henri-Robert wrote: > Hi, > > We have an xwiki 6.1 installation and we can't figure out the « Share page by > email » function. > > It works very well for Admin users, but it doesn't work for regular users.
