Hi,
I've installed WordPress, then loaded the Be-theme (inkluding all required stuff). Afterwards I importet the Demo "Simple". After an hour of configuration the menu bar was gone (header = center), only the menu item (3 lines) is there. Only if I deactivate "Responsive", I can see the menue line (5 Links) but not centered?!
The next thing I tried was to delete the whole homepage from my server and started from the beginnen, istalling WordPress and so on... But when I looked on the page, the problem wasn't gone. Sorry, I'm a newbie. Thank's for your help!!!
