Adding a new menu item failes when saving

Hi,

I have a site where I cant add an menu item in the Apperance – Menu.

I can add the items in the list, but once I click save the following happens:

– The menu item isnt savned (it get as before)
– The menu gets removed from its location (catnav) and I have to replace it in the “set position”.

Everything worked well before, but suddenly it didnt work any more. The one thing that has happen is that the SQL database is moved from 5.5 to Maria 10.0 by the host.

I have tried following:

– Innstaled an earlier Version 4.3
– Move everything to a New database With 5.5
– Deactivated all plugins

But nothing Works.

When I use debugging I get the following:

already defined constructor for class googlefonts in /home/3/o/ossia/www/wp-content/plugins/wp-google-fonts/google-fonts.php on line 140
