Since upgrading to version 5.0.3, I am unable to log out. Each time I press Disconnection it shows the disconnection page, but then it says "Loading" and loads the user again. I am using Google Chrome in Windows OS.
Only way I can log out is by clearing the cache.
Cannot reproduce.
Could you please check for errors in log file and browser console..
I have an hint : this kind of issue can happen if you get a PHP error during the deconnexion.
So please check your log file and post here any error reported.
I cleared cache browser, closed Chrome and reopened it and the problem appears to have fixed itself.
