Hi Alexandre and thanks for the fix! I have installed 15.1.15, verified that it solved the two reproducible cases I mentioned first, and already patched our production environment. The flow of error logs from our maintenance systems regarding "Invalid page context" seems to have stopped (although it is perhaps a bit early to draw final conclusions), except for one case which is the one described in one post above where you get two simultaneous sessions for the same user agent and IP for our mobile web application. This is not reproducible for me. I will look into this case a bit more and let you know if I find some useful information. But the for most parts the error seems fixed, so thanks again for that!
