UI broken, page unusable

Hi,
i couldn't help but notice that the navigation does not work anymore because of a JS error, so it is impossible to navigate the page at all (without modifying the css manually).
As this has been going on for at least a couple of days and noone seems to notice, i can't help but wonder, is this page even being maintained anymore?

Or is this just a dead husk still trying to sell stuff without any support?

Happy to hear a sign of live,
cheers,
Lars

p.s.: if you need help fixing the page, don't hesitate to contact me ;p

Still broken, page dead?

Do you receive an error at the moment?

Yes, still.
The menu JS is not working as there is an error that crashes th JS on the site.
None of the dropdown menus are working!
Not for logged in users nor for visitors.
Error in extr213.js:2:525, trying to get scrollHeight of null

Needless to say i can't edit my comment either as no js works on the page.
I meant the file extra213.js obviously

so apparently the element #messages-list is missing and there is no check for it's existence before you try to get its scrollHeight

Still broken...

Still broken.
It makes the page almost unusable, it should be an easy fix as well, just add a null check before trying to access the element's scrollHeight here:

$(document).ready(function() {
var elem = document.getElementById('messages-list';
elem.scrollTop = elem.scrollHeight;
});

Hello, for several weeks I have not been able to access the download panels for the files I purchased, nor my profile, nor the messaging, I click on it and nothing happens. How can I solve this problem? It's urgent, thank you!
