 When you are using preferences data from Horde 2.x with Horde 3.0, you have
to delete all {{last_login}} preferences, as mentioned in the
[http://www.horde.org/horde/docs/?f=UPGRADING.html#upgrading-horde-from-2-x-to-3-0-x
upgrading instructions]. This could be done with an SQL statement like:
 <code>
 DELETE FROM horde_prefs WHERE pref_name = 'last_login';
+</code>
+
++++ Users using Internet Explorer always get a blank white screen. Other
browsers work fine.
+
+Internet Explorer has known problems with the combination of HTTP-1.1
keepalive and SSL encryption. Many Apache configurations use a
!BrowserMatch or !SetEnvIf directive, like this one, to solve this problem:
+
+<code>
+SetEnvIf User-Agent ".*MSIE.*" nokeepalive ssl-unclean-shutdown
downgrade-1.0 force-response-1.0
 </code>
