Would this also be the issue I am seeing on my family sites? When I'm on the initial page, or the Home tab, all I get is the blue bar across the top and no tabs. I can go and use the left hand side menu and click on the link View Family Tree, and then I see the tabs across the top. However when I click the Home tab again it brings me back to the page where all I have is a blue bar at the top, is this also due to the screen resolution? Let me know if you need anymore information about what I'm seeing.
Your problem doesn't sound connected to the menus being pushed to a second line. You wouldn't have a problem seeing the rest of your family site if it was just the menus.
Your problem sounds different. Can you try to clear cache and cookies in your browser or try using a different browser altogether?
If you continue to have trouble, take a screenshot of what you see and either attach it here in the thread or send it in an email to support@myheritage.com and we'll take a look.
I have took a screenshot of what I am seeing. First the one with Home in it, it is of the screenshot of what I see upon initially logging in or pressing the Home tab in the second screenshot. The second screenshot contains the event page (I navigated to it by clicking the View Family tree link on the left hand side, and in order to not have the names I then was able to click on the events tab). It just seems like when viewing the home page I should still see the tabs, correct? Let me know if you have any questions or would want me to include anything else.
