Thanks for providing me a test user, I got this weird error:
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
<title>406 Not Acceptable</title>
</head><body>
<h1>Not Acceptable</h1>
<p>An appropriate representation of the requested resource /webservice/rest/server.php could not be found on this server.</p>
<p>Additionally, a 404 Not Found
error was encountered while trying to use an ErrorDocument to handle the request.</p>
</body></html>
Can you check if you have a firewall, proxy or the webservice directory deleted or disabled by you web server settings?
It seems a configuration problem in your site
Cheers, Juan
