When mousing over items no data will be displayed anymore, it stays at "loading". I thought it was something related to the website untill when mousing over items on the store I noticed the same thing happening, and after clicking on the item I saw that the website http://wotlk.cavernoftime.com/ is apparently down. Maybe you could use another database in order for the armory to work again. Possible websites:
I have a similar problem with store. I have the sword from illidan main hand, and I want to buy off hand too, but I can't figure out which sword is off hand because they have the same names.
