[Resolved] Menu maintenance defective

[Jens]

For the third time the menu maintenance is destroyed by some kind of action.
I can only fix it by uninstalling and reinstalling the theme. But then a large part of my work is destroyed.
Do you know the problem and do you have a solution?

Hi there,

What is menu maintenance?

This doesn’t sound like a theme issue – the menu builder is a WordPress core function.

We haven’t had any other reports on this either.

Have you tried disabling all plugins except GP Premium to test?

I can only fix it by uninstalling and reinstalling the theme. But then a large part of my work is destroyed.

Doing this shouldn’t fix anything and have any impacts on your site unless you’ve added some code in the parent theme’s files.

It’s never a good idea to modify the theme’s core files – changes should be done in a child theme:

Hi Leo,

I mean the area where I can create or update a navigation.

Image from navigation area and the error massage.

I disabled all other plugins but the problem is still there.

I used only the webinterface to change the style.

Hi there,

can you make sure you have downloaded the latest version of the Theme ( 3.1 ) and the GP Premium plugin ( 2.1 ). And those are installed.

[Jens]

Hi David,

yes I have the newest Version because I started only for a few days ago.
I find the problem but I can’t solve it.

If I change the “Homepage settings” form “You latest posts” to “A static page” than I get the problem with the navigation.
If I switch back to “You latest posts” the error is disappeared.

But I would like a static page as start page. Do you have a solution for that? Mayby you can reproduce the error withe the same template.

I use the theme “Marketer”.

[David]

What is on the Static Page you are setting in the Homepage settings?

[Jens]

Hi David,

the static page is completely empty. No special content in this page.

I guess this is not the problem from the page. If I defined a other page as static page, I get the same error.

Hi Jens,

Can you try to create a new static page, name it Blog, then assign it as the posts page while you assign the static home page as the home page?

Let me know if that helps.

[Jens]

That works .. thank you so match.

[Ying]

You are welcome 🙂
