Hi all,

I have completely lost access to my Umbraco back office. When I access the url:

localhost:50275/umbraco

the url is changed to

http://localhost:50275/umbraco#/login/false?returnPath=%252Fumbraco

All I did was edit the html and CSS of a dashboard in Visual studio. I then ran the project and this happened.

I have enabled Firebug and the following errors are present in the console but I do not understand why they would be there when I haven't done anything with Javascript:

    ReferenceError: jQuery is not defined

    (function(t,e){function i(e,i){var n,o,a,r=e.nodeName.toLowerCase();return"area"...

    TypeError: $ is undefined


    var originalAdd = $.blueimp.fileupload.prototype.options.add;

TypeError: $ is undefined


$.blueimp.fileupload.prototype.options.processQueue.unshift(

$.support.fileInput = !(new RegExp(

...([c,d,arguments]);return m}}if(!e)throw Error("No module: "+d);var b=[],c=[],j=a...

TypeError: UmbClientMgr is undefined


UmbClientMgr.setUmbracoPath('/umbraco');

Does anyone know how to resolve this issue as at the moment I cannot do anything with my Umbraco installation because of this frankly unhelpful set of error messages.

Any help would be greatly appreciated.

Kind regards,

Jason Espin
