Menu Broken: Items disappearing/moving/changing type

Have you tried:

– deactivating all plugins to see if this resolves the problem. If this works, re-activate the plugins one by one until you find the problematic plugin(s).

– switching to the Twenty Eleven theme to rule out any theme-specific problems.

– resetting the plugins folder by FTP or PhpMyAdmin. Sometimes, an apparently inactive plugin can still cause problems.

Thanks, esmi.
However I tried what you suggested and it’s still the same.
I also tried creating a completely new menu, but I get the same problems.
Menu items moving and changing type.
Perhaps some items in the wp_posts table are corrupt. I read that the Menus are also stored somewhere in there… I’l try to investigate that…

If your issue is that you can only ever have a maximum of x amount of menu items, this is a server issue.

Get your host to enable/increase suhosin on the server and your problems will disappear!

suhosin.post.max_vars = 5000
suhosin.request.max_vars = 5000

Hmm, at the moment I can’t change suhosin values. Anyway, would that explain that Menu items are changing their type?
My menu isn’t that large; And I also have Problems when submitting my menu with around 70 POST variables while suhosin.post.max_vars is at 200.

You can’t change suhosin yourself and may need to contact the host. It may not be that causing the issue, but it’s worth a try. ??

I know. But i remember having Problems with sorting Pages, too. I’ll give it a try.

Setting the values to 5000 fixed it.
Thanks everybody!

I met same problem. I first increase to 2045 and it worked fine only for a few days. Moreover I could not use model templates too. Now settings are 5000 for both vars. It’s fine. Hoping it would work for long time. Btw, I cannot save any settings with various SEO plugins (All in One, Meta SEO, High Performance SEO……). I tought it was same issue but in fact not. Still looking for solution.
