On some pages this error occurs:
Also it happens when you press finish editting.
There is no error in the event log on the Tridion CME, no entry in the event log on the presentation machine. There is no error in any of the tridion log files or application log.
I've checked the logs on the CME, the logs for the odata service, the website, the deployer, everything...
I've quadruple checked the configurations on all applications. Everything looks fine.
It is a website running on DD4T with Tridion 2013 sp1. Everything is published and retrieved from the broker. Binaries as well. No static file are being published.
It looks like the ambient data http module is generating this error, but is not reporting it.
Has anybody seen this error before? Or does anybody have a clue what is going on here?
