Create and Usermenu Items Are Not Showing

[Robiss767]

Hello. I am trying to create a page using HTML and I'm using some javascripts. When I view the page, everything works, including the javascripts. However, once I click on "Create" or my profile (header of page), nothing happens. The list of create items and usermenu items are just not appearing. I've been doing plenty of testings, spent like 5 hours and still did not manage to get it to work.

When I remove the javascript, it works. When I remove some lines of javascript to make the script bugged, then it works as well. 

Does anyone know what I should/can do?

Thanks.
