Hi @leonie12 For the logout button, assuming you've got userHelper activated, you can simply use a normal link anywhere within your template, it doesn't have to be called by the FormLister snippet (no need to use the skipTpl):
For me, the 8 ID above is the login page - but I don't think it matters which page you link to.
For your redirect loop I think it depends what page 10 is doing and what permissions it has, sounds like maybe your user doesn't have permission to view page 10 so it's redirecting back to your unauthorized page? I've tried &redirectTo=`` and it's working fine for me.
I've started fresh with this site so don't know about prepareToUpdateFrom2To3Evo
Pathologic has been amazing at solving issues I couldn't figure out.
