<p>Hi Chris,</p>
<p>Are you are running owncloud on a server with php xcache running? Recently I had a similar issue upgrading my owncloud 6 and also installing it on another server. The white screen of death seemed to be caused by misconfigured xcache php extension, or more accurately, xcache needed additional configuration other than the default for owncloud6 to work.</p>
<p><br />On Debian style systems, you would know you are running xcache by having the php5-xcache package installed and a file /etc/php5/conf.d/20-xcache.ini</p>
<p>In my 20-xcache.ini file I had to make the following changes:</p>
<p style="margin-bottom: 0cm;" lang="zxx"><span style="color: #000000;"><span style="font-family: Lucida Console,serif;"><span style="font-size: small;">[xcache.admin]<br />xcache.admin.enable_auth = On ; </span></span></span><span style="color: #000000;"><span style="font-family: Lucida Console,serif;"><span style="font-size: small;">ensure this is set to on<br />; Configure this to use admin pages<br />xcache.admin.user = "</span></span></span><span style="color: #000000;"><span style="font-family: Lucida Console,serif;"><span style="font-size: small;">SOMEUSERNAME</span></span></span><span style="color: #000000;"><span style="font-family: Lucida Console,serif;"><span style="font-size: small;">" ; </span></span></span><span style="color: #000000;"><span style="font-family: Lucida Console,serif;"><span style="font-size: small;">uncomment and config this<br />;xcache.admin.pass = md5($your_password)<br />xcache.admin.pass = "</span></span></span><span style="color: #000000;"><span style="font-family: Lucida Console,serif;"><span style="font-size: small;">MD5HASH OF YOUR PASSWORD</span></span></span><span style="color: #000000;"><span style="font-family: Lucida Console,serif;"><span style="font-size: small;">" ; </span></span></span><span style="color: #000000;"><span style="font-family: Lucida Console,serif;"><span style="font-size: small;">uncomment and config this</span></span></span></p>
<p style="margin-bottom: 0cm;" lang="zxx">...</p>
<p style="margin-bottom: 0cm;" lang="zxx"><span style="color: #000000;"><span style="font-family: Lucida Console,serif;"><span style="font-size: small;">[xcache]<br />; same as aboves but for variable cache<br />xcache.var_size = 16M ; </span></span></span><span style="color: #000000;"><span style="font-family: Lucida Console,serif;"><span style="font-size: small;">was set to 0 by default<br /></span></span></span></p>
<p>However, if you're not running xcache then the error.log is your friend debugging this problem.</p>
<p>Regards,</p>
<p>Scott Bragg</p>

<pre>Hi,
most times a white / blank pages means an internal server error.
Check the logfiles of your webserver and PHP to get a hint
whats wrong here.</pre>
