Fails to export or import menu items when using PHP7

Hi there,

I tried to export the menu (inkl. its items) from a staging site and import it into the production site, because the only new thing about the staging site ist the theme, the theme options and the menu structure.

When using php 7.0 the menu itself and the underlying pages are imported as well as any media within these pages – BUT – the menu structure is not imported, i.e. the menu items do not appear in the imported menu.

After changing back to php 5.6 the export/import works as expected: the menu including all its submenues and all of the menuitems are imported as well as the underlying pages with their media.

Could you please fix this issue? Or is it an issue in the wordpress importer?

Thanks in advance
Thomas
