Disabled update button in wordpress

Using Visual Composer and some other VC addons to design my page. After a couple of additions to the page through those plugins the page autosaves disabling both, preview and publish buttons indefinitely. I have limit the time Wordpress autosaves by following the steps in your tutorial, but I understand that is not the proper solution because once I go back to the normal autosave intervals the issue comes back.

How can I find what is conflicting with autosave making it stall?
