This is the first time I have ever run into a bug on my xenForo installation so I will do my best to report as much as I can. Basically, when I try to post a thread I get no joy at all, I get an error window pop up but can't see all the way to the bottom as the box is hovering. Below is what I can see from it. As I say, there could be more but I can't scroll down to see any more! Any help would be greatly appreciated in the matter.
