http://www.istockphoto.com/forum_messages.php?threadid=223181&page=11#replyRest assured we have people working on things. Sorry for the trouble, folks. The thread linked above is where everyone is commenting. One thing I will leave with you all is a short list of the errors we have received so far:
1. Uploads Page is unavailable.
2. Detailed Catagories box in the uploads section is not working properly
3. error 4004 (you do not have the correct access level to use this class) while trying to add keywords through DeepMeta.
So, if you are one of the people who have been given a forced day off from uploading at iStock it's probably due to the missing Uploads Page. However, if you are experiencing any additional errors please feel free to either add your issue to the thread linked above, PM me here, or send me a site mail at iStock.
Lobo out.
