We recently updraded to v5r3 on our i5 and installed our new Apache server. We had web-apps running in RPG/CGI for months before the upgrade. The code hadn't changed, yet after the upgrade, the web-apps started to not work as designed or would not do anything when a form-button was clicked or sometimes a screen error on the browser. We changed all the forms to execute a "GET" instead of a "POST" and the apps work fine. Has anyone experienced this? Operations says it's the code, the code wasn't changed. Is this a set-up issue? PTF?
