After installing UberMenu (plugin) I can't save my menu anymore. Even if I disable (and delete) this plugin, I can't save my menu.
I don't know for sure if it is caused by this plugin, because I have deleted all the files of this plugin.
Also when I disable all my plugins and switch to another theme, it is not working.
I'm using WP 3.6 Dutch version, but I don't think that's the problem.
