Staying logged

Hi,
I bought the theme last year, implemented it, but I still have an issue with staying logged in. To be more clear: after I login with my credentials I am redirected to my personal page. If I want to go back to front page and click home button or the logo in the header it gets me out of my account! It seems like the application forgets that I’m still logged in and I have to refresh the page to be logged in again?
Please advise!
Thanks!
