I am gettings lots of Javascript errors on my SharePoint site. It is causing a lot of issues when you log into the SharePoint site internally and externally, it also doesnt matter what browser I use, the menu toolbar at the top will not load when you move between 'page' and 'browse' and just displays 'loading' and nothing happens. Also when you click 'add document' or 'upload a document' nothing happens. It did work fine but stopped when I published my site through my Forefront-TMG with alternate access mappings. Setup is:

User enters https://share.domain-com into IE from an external location . Traffic gets to Forefront-TMG and performs a reverse proxy and bridge to http-://share.domain-com.

AAM's for my site are:

    Internal URL = http-://servername, zone = default, Public URL = http-://servername
    Internal URL = http-://share.domain-com, zone = Internet, Public URL = http-://share.domain-com

I have also setup bindings in IIS7 as follows:

Site Name = SharePoint - 80

    Binding 1 - Type = http, Host Name = (Blank), Port = 80, IP Address = *, Binding = (Blank)
    Binding 2 - Type = http, Host Name = share.domain-com, Port = 80, IP Address = *, Binding = (Blank)

The Javascript errors I get when I log into the page are:

I have no idea what I have done to cause this as my SharePoint is now unusable, tried to remove AAM's etc to put it back to how it was but it made no difference.

Does anyone have any idea how I can rectify this and get my SharePoint working again internally and externally?

Some time ago I noticed that for a site that was published through an ISA Server AAM was not enough, I got a lot o js errors. I had to extend my web application and everything started working fine.
