This has been (de)bugging me for quite a while now, have anyone else experienced and solved a similar issue:
We run the same xpage application on two different servers. One is the good old development server stil running on 8.5.1 and the other the production server running on 9.0.1
Everything works beautifully on the 8.5.1 server but when we test it on the 9.0.1 server we find some random xpages throw a http500 error
What makes it unusual to me is that a page working perfectly on the 8.5.1 server throws an error on the 9.0.1 server.
The build is in a 9.0.1 designer client so that should not be an issue, but apparently some other compatibility problem is.
Any input welcome!
