I am running the latest release version of Google Chrome on Windows 7.
My favorite addons page is completely empty and if I click and individual addon the page is empty as well (except for the header text).
I am not sure if this has anything to do with me registering for a premium ZAM account which has so far been unsuccessful (premium not enabled on wowhead for instance)
edit: tried to delete all cookies on Wowinterface and logging in again and that didn't work.
I'm using google chrome latest version my self on win7 and osx and everything displays fine. Infact I just tested and it displays fine in all browsers.
Did your username change on wowinterface?
Is it just a certain addon page or all of them? What chrome addons do you have enabled? Does it work in IE or Firefox?
If you change your email address in wowhead to the same one as zam and wowinterface you should get premium. you'll have to log out and back in on wowhead.
Looks like you have some addons installed on your browser, just for testing could you disable them temporarily and see if the pages render? I'm not using any addons on my chrome and the page renders correctly for me.
I havent received any other reports and chrome is a heavily used browser with addon authors so I think we need to figure out whats happening on your end.
