Oh, alright.
Well, i think i got ion_auth files from here (http://jondavidjohn.com/blog/2011/01/sca...r-ion_auth)
Where is says "Download Here". Now idea if it's the newest version.

Now, if i have an older version, do i have to download the newest version from github and configure everything again? Or is it a smarter way, where i can like "upgrade" current code?
