Redirect without login

Hi!

Last week un updating EE 2.5.5 to 2.9.2 and then update some modules website runs fine but I discovered that if I login in CP, the REDIRECT label works perfectly but if I visit the front-end without user access or no access to CP redirection fails and displays a blank page.

Someone can tell me any idea where is the problem?

I’ve looked at a lot of sites do not find a solution.

Thanks

PS: I use the “Channel files” module and have found that if the user logged on to the CP, downloading and running, but the user does not have access to CP or a guest does not work and I think it is the same problem
