Modpack Description Editor fails to load

[Noricum]

Heyho,

since today in the morning the GUI-editor doesn't load my data at all...stay gray :/

Here, take a look:

I already tested it on 3 different devices and 4 browsers (2 PC's + 1 iPad, Chrome,Firefox, Safari , Internet Explorer) but its always the same. Even if i edit it using BBcodes, it doesn't save my new inputs.

Could anyone help me?

Edit: I know what causing that error, but i can't undo in my description...There is a empty ... this let the editor "explode" :/ *bug*
