andybonner replied the topic: Authentication - Email
Thanks! I look forward to hearing. The apostrophe works in the password field.. just not when it's in an email address and that's used for the username... not good for the Irish where O'Sullivan, O'Brien, O'Neil and many other names like that are of course commonplace!!!
OK, it seems that the Joomla authentication fields are populated using some kind of filter that removes apostrophes (and, presumably other characters that I can't be bothered to test...because there's no point)
Anyway, now that I know that there's a filter in place, I don't trust the username field to convey the username as entered and I go directly to the raw input and things work as expected.
I need to do some more testing before I release a new version, so give me a bit and you'll see an update available with in the Joomla updater within the next day or so.
