Update: I get the following error when I try to access the datastore index link again:
Server Error A server error has occurred. I am not sure if this error is related to the index problem, or to exceeding quota. Please note that the quota was not exceeded when I post the last error / exception message. It is very strange now as I was able to click into the datastore index page/link when I posted the last error, but now I can't even access it anymore. And I am having trouble deploying the modified application. I get errors saying it failed to upload / create the index at the server. I wonder if something is wrong with the index on the server right now? Is anyone else having similar problems? Any light would be appreciated.
