Link Option in WP-admin/menu don't work

Hi,

Does the other options on the menu page work (can you expand/collapse the Pages one for example), or are they all “stuck”?

If they are all stuck, try disabling your plugins and see if it works then, you might also want to try changing to one of the default themes (such as Twenty Fifteen which is the latest one as of this posting) and see if things work then.

If everything works as expected at this point, try enabling things one at a time until it stops working and you should know what plugin/theme is causing the problem.

I have the same problem. On the Menu page of theme Twenty Fifteen the link and category options will not open. The Pages option is open, but I can’t close it.
I have disabled all the plugins, but that doesn’t help.

What should I do now?

Thanks in advance

Rob

Can you give me your URL or screenshot

I have put a screenshot on https://italics.net/expand2.jpg.
(It’s the Dutch translation of theme Twenty Fifteen of WordPress 4.1.1.)

Its jQuery conflict problem

May i know your plugin list

I have disabled all of my plugins.
I have visited the admin with IE, Chrome and Firefox.
And I have changed the theme to Twenty Thirteen and Twenty Fourteen.
Nothing helps: in all situations I have the same problem.
Strange?
