SOLVED Front end content/ Visitors accsess problem

Hello,
Visitors of our site complaining about this

Message You do not have permission to go to this area

.
For example at page categories list "Detached houses" is available to anyone, when you choose another category, visitor have access problems. They see "Message You do not have permission to go to this area." Same problems we deal and another content like properties.
I have checked access at categories is public everywhere. What can I do?
Thank you in advance!
