Error 500s are almost always caused by a misconfigured .htaccess file. If you have one in your main website, try renaming it and see if the error goes away. If it does, you could put a blank .htaccess file in the userspice root. Let me know what happens, because I might put a blank one in the userspice root by default to stop this from happening.
