we're developing web application using the Wt framework (https://www.webtoolkit.eu/wt). Suddenly, after some ESS update, the application stopped working, because http headers become "corrupted", the "Transfer-Encoding: chunked" being inserted to http headers. It took me almost 4 day to find out, where the problem is! When the ESS is uninstalled, everything is working ok. If ESS is installed, BUT not updated, everything is working ok. If ESS is installed and is updated, the application stops working.
I'm using Windows 7 64bit Pro, ESS 9.0.376.1, ESS database version 13731.
Anyone could shed some light on this?
