The problem is, its a clients’ production server and I have very limited information about the host. Since things have worked there so far without issues, all I was provided with was FTP and required db credentials.
I’ll try and find out that bit about web cache though.

Thanks much!

I saw your post after posting my reply and I was actually thinking on the same lines – some server problem (but no idea what exactly), as I already tried a clean install of the whole thing for a second time. Can’t go wrong twice on that one. ??

But then, everything else works, so how come!

Weird that whatever the issue is with the plugins folder (assuming that is the issue) it triggered without ever activating the plugins and it affected only the functionality of wp-admin/nav-menus.php from observations so far. Foxed, I am.

Oh well, wait… It works!

Meh, it will remain a mystery to me what fixed the issue, but it works now.

I already had it set to default theme, default permalink structure, with no plugins activated whatsoever.

Recollecting the last thing I did following your post (@esmi):

“Resetting the plugins folder” using FTP. It again gave the same errors once, but worked on subsequent attempt.

Not sure what fixed it. ?? It works with my theme too now! ??

Thanks much esmi! Perhaps it was the plugins folder!
Cheers!

Hey esmi, thanks for your reply!

I have tried all the points you suggested. I did not activate any plugins at all since i set up the site and it only has the default packaged Akismet and Hello Dolly plugins in the plugins folder, but I did the “resetting the plugins folder” step anyway.

Also, default twentyten theme with the default permalink settings didn’t work either in this case. It still fails to save the customized menu and immediately throws a 400 Bad request error (if permalinks are set to some nice url the error thrown is 404 Page not found as I mentioned in my first post).

I am trying to save the menu over and over, hoping that if there is something wrong on the server, it might work as soon as it is sorted out. :S

Hey ixwa, thanks for your reply! I’ll make sure I check that when I use categories in the custom menu.

However, in this case, all the pages linked to from the custom menu have been already published and have titles and content in them. The default links I have on the theme work fine too. Just that I am not able to customize the menu the way I want _and save it_ using the Menus editor in the dashboard.

Also, the code used in the theme to get those page links in an unordered list ( using a call to wp_nav_menu() ) works fine on my local test machine.

Thanks for your time though! ??
