I had made a site, and everything worked until the menu disappered from the Apperance/Menues. I tried to make a new menu, but then the pull-down menues disappeared. Only the top-pages was left. When I removed the new headermenu, the website obtained its previous state.
But it is impossible to live with a headermenu I can't edit. So I tried to change the theme to see if this problem was connected to the theme. But it remained in the website with another theme. So it must have a connection with the content.
I have updated to WordPress 3.5.1.
I thought I did the update after the problem occured, but not absolutely sure. I had also installed a plugin named Captcha. At the frontpage I had set one static page, opposed to the 'last posts'.
I didn't test between, so I'm not sure what caused this.
Can someone help me please? I'm a newbee and desperate :-)
