<Object [object Object] has no method 'infinitescroll'> after plugin re-uploaded to server

Question

I'm getting an error for infinite scroll in my tumblr blog.

Uncaught SyntaxError: Unexpected token < jquery.infinitescroll.min.js:6
Uncaught TypeError: Object [object Object] has no method 'infinitescroll' 

The thing is, I haven't changed the code at all. It worked fine before I accidentaly deleted all of the .js from my server. Now after I reuploaded the files, it doesn't want to work.

console.log(jQuery.infinitescroll);

returns "undefined".

You are missing infinite scroll plugin.

You do include it in your header:

<script src="http://www.gamepad.lt/tumblr/js/jquery.infinitescroll.min.js"></script>

However this link does not contain the jQuery code for the plugin (!):

http://www.gamepad.lt/tumblr/js/jquery.infinitescroll.min.js

Update the file with the code for infinite scroll plugin.
