Expected and actual behaviour
Server should reply something else than “500 internal server error” when connecting to it. That’s what my client reports.
Opening in a web browser should display the oc file explorer. White page is shown instead.
This server has worked fine until a recent software update (webserver, DB and others).
I wish, to repair this and/or to upgrade to newer version of the server (my clients started complaining about outdated server version recently).
