Loop for Logout

Hi there , i've been testing my site and i have had a loop issue whenever i try to logout from my account . even after i click on logout on both the main menu and the side bar menu i configured, it seems to re-direct me to the same page i was logged into.

i have checked the backend to configure it to redirect to a different page, but it keeps showing me i am logged in again (e.g via the main page).

can someone help and advise how to address this issue ?

thank you!
