The problem is now solved. The hosting company had messed up entries in the php.ini file – and reducing memory to zero. I only discovered this accidentally.

The problem persists: I cannot delete pages in the menu.
I did deactivate “WP Super Cache”. At least is it shows it is deactivated.

Correction to last post: the home page is now correct, showing the menu.

Something else is wrong:
Having switched to twenty-fifteen theme, the menu does not show, and the correct home page does not show. I have changed the home page several times to different pages, but the home page continues to be a ‘post’ page, and not a static page (despite having ticked that box). So the setting is correct but the result is wrong.

Yes, I am trying to change it under Appearances > Menu.

I have now de-activated all plugins and I switched to the theme twentyf-fifteen, as sugggested above, but again, I cannot remove any pages from the menu. Whenever I press ‘Save’ they appear again.

I am trying to remove from the menu all the pages regarding the riding simulator. I deleted one page but of course that did not remove it from the menu – just shows ‘page now found’.

Yes, I have tried to clear cache. Also tried to re-install WordPress.
