Hi Rob,
We have followed the steps that you set out and were unable to replicate the problem. I have attached the config file in which I have replicated your steps. I have tried this on both version 3.1.3.1 and the release candidate (version 3.4.4.12). I recommend you update to version 3.4.4.12 and load the config fiel that I have attached into your Miniserver.
Can you please tell us what web browser and which version of it you are using?
Error 500 is a standard error code for webpages, that indicates some error when communicating with the webserver, so it could be that some browser setting are causing it.
If you continue to have problems, please feel free to contact us via the Live Chat so we can set up a screen sharing session to help you out.
Best Regards,
Philipp
