Since the site on our internal environment we cannot provide access to it. I have attached an image of the error we are receiving when attempting to add attachments in FireFox.
A couple of other things that are happening is that in FF when you click on "Add Category" it takes you out of the add article feature and back to your main page.
Also in FireFox and Chrome the articles are not appearing after you have clicked submit. In FireFox the only way to get to that step is to avoid adding attachments and a category.
Any help is grealty appreciated! Thanks!
