I have javascript disabled by default in my browser, manual enables only. When I load the webconfig for an Antminer, the pool config fields always come up blank. I don't know Chrome so I don't know about how it handles scripting, that's just what I've seen causing similar symptoms. Could be something completely different.
You might SSH into the miner and see if the pool config file exists or is corrupted. What do you see on cgminer status on the webconfig?
The monitor shows...
