<h2>Debugging the issue<a class="headerlink" href="#debugging-the-issue" title="Permalink to this headline">¶</a></h2>
<p>In a standard ownCloud installation the log level is set to “Normal”. to find any issues
you need to raise the log level to “All” from the Admin page.
Some logging - for example JavaScript console logging - needs manually editing the
configuration file.
Edit <tt class="file docutils literal"><span class="pre">config/config.php</span></tt> and add <tt class="docutils literal"><span class="pre">define('DEBUG',</span> <span class="pre">true);</span></tt>:</p>
<div class="highlight-python"><pre><?php
define('DEBUG',true);
$CONFIG = array (
... configuration goes here ...
);</pre>
</div>
<p>For JavaScript issues you will also need to view the javascript console. All major browsers
have decent developer tools for viewing the console, and you usually access them by
pressing F-12. For Firefox it is recommended to install the <a class="reference external" href="https://getfirebug.com/">Firebug extension</a>.</p>

<h2>Service discovery<a class="headerlink" href="#service-discovery" title="Permalink to this headline">¶</a></h2>
<p>Some clients - especially iOS - have problems finding the proper sync URL, even when explicitly
configured to use it.</p>
<p>There are several techniques to remedy this, which are described extensively at the
<a class="reference external" href="http://sabre.io/dav/service-discovery/">Sabre DAV website</a>.</p>
<div class="section" id="apple-ios">
<h3>Apple iOS<a class="headerlink" href="#apple-ios" title="Permalink to this headline">¶</a></h3>
<p>Below is what have proven to work with iOS including iOS 7.</p>
<p>If your ownCloud instance is installed in a sub-folder under the web servers document root, and
the client has difficulties finding the Cal- or CardDAV end-points, configure your web server to
redirect from a “well-know” URL to the one used by ownCloud.
When using the Apache web server this is easily achieved using a <tt class="file docutils literal"><span class="pre">.htaccess</span></tt> file in the document
root of your site.</p>
<p>Say your instance is located in the <tt class="docutils literal"><span class="pre">owncloud</span></tt> folder, so the URL to it is <tt class="docutils literal"><span class="pre">ADDRESS/owncloud</span></tt>,
create or edit the <tt class="file docutils literal"><span class="pre">.htaccess</span></tt> file and add the following lines:</p>
<div class="highlight-python"><pre>Redirect 301 /.well-known/carddav /owncloud/remote.php/carddav
Redirect 301 /.well-known/caldav /owncloud/remote.php/caldav</pre>
</div>
<p>If you use Nginx as web server, the setting looks something like:</p>
<div class="highlight-python"><pre>url.redirect = (
"^/.well-known/carddav" => "/owncloud/remote.php/carddav",
"^/.well-known/caldav" => "/owncloud/remote.php/caldav",
)</pre>
</div>
<p>Now change the URL in the client settings to just use <tt class="docutils literal"><span class="pre">ADDRESS</span></tt> instead of e.g. <tt class="docutils literal"><span class="pre">ADDRESS/remote.php/carddav/principals/username</span></tt>.</p>
<p>This problem is being discussed in the <a class="reference external" href="http://forum.owncloud.org/viewtopic.php?f=3&t=71&p=2211#p2197">forum</a>.</p>

<h3>BlackBerry OS 10.2<a class="headerlink" href="#blackberry-os-10-2" title="Permalink to this headline">¶</a></h3>
<p>BlackBerry OS up to 10.2.2102 doesn’t accept a URL with protocol <tt class="docutils literal"><span class="pre">https://</span></tt> in front of the server address.
It will always tell you, that it cannot login on your server. So instead of writing</p>
<blockquote>
<div><a class="reference external" href="https://address/remote.php/carddav/principals/username">https://address/remote.php/carddav/principals/username</a></div></blockquote>
<p>in the server address field, you have to write</p>
<blockquote>
<div>address/remote.php/carddav/principals/username</div></blockquote>

likely caused by one of the following reasons:</p>

<dt>Outdated lighttpd web server</dt>
<dd>lighttpd in debian wheezy (1.4.31) doesn’t support the PATCH HTTP verb.
Upgrade to lighttpd >= 1.4.33.</dd>

<dd>As of writing this Pound doesn’t support the HTTP/1.1 verb.
Pound is easily <a class="reference external" href="http://www.apsis.ch/pound/pound_list/archive/2013/2013-08/1377264673000">patched</a> to support HTTP/1.1.</dd>
