Im having issues approving or denying item requests on the web site. the little pop up screen displays, but when i say submit it dissapears and nothing changes on the site.

Wanna bump this. Now having the same problem.

I can't find out where to see Item Requests outside of the little red pop-up bos.

Item requests are found in the "Request for Item" section. They're created by clicking the "Req" on the Guild Bank page.
