Hi,

I have a website running over Umbraco 4.0.3 and have recently been facing a weird issue on the backend interface. Every time I try to delete an article, sort a folder or save a template (either by clicking the button or pressing Ctrl + S), my Firebug throws a JavaScript error and does not perform the intended action.

Example with the Sort functionality:

Once I click the Sort button on the contextual menu, the modalbox comes up and I can arrange the items on the list. But when I actually click the Save button on the modalbox, the following error is thrown on Firebug:

umbraco is not defined
sort()
onclick()
event = click clientX=28, clientY=391

umbraco.presentation.webservices.nodeSorter.UpdateSortOrder(3814, sortOrder, showConfirm);

So, the folder does not get sorted and the modalbox keeps saying "Please wait. Items are being sorted, this can take a while." forever. I'm positive no articles are sorted, even after 10 hours. It seems to me like this JavaScript exception is being thrown and preventing the desired action from being triggered.

Funny thing:

I noticed this started happening when I was deleting an entire Media folder and some of the Media items inside didn't actually have a physical file associated (the umbracoFile property had something else instead a file path). Could these requests be queued up and block other actions?

I already tried moving it to a brand new Umbraco instance... It worked fine initially but the same problem arised when I tried to delete a similar Media folder.

I'm stuck with this and would appreaciate any ideas.

I really don't know what else to do!

Thanks in advance!

Andre
