was facing same problem of session with IE 8. Many threads suggested for underscore, timezone difference. Real problem is timezone difference. CI creates cookie with server time and IE checks expiry related to client timezone. And here issues comes. You can not change time zone of online server to match clients from all over world. The better solution is change cookie / session expiry time. By default it is two hours. Change it to 24 hours and problem will be solved.

In config.php file change value of following variable

from two hours

$config[‘sess_expiration’]      = 7200;

to 24 hours

$config[‘sess_expiration’]      = 3600 * 24;

Fatal error: Class ‘MY_Controller’ not found in application\controllers\welcome.php on line 4

then reasons can be

1. you are either not loading it properly (via an __autoload() or manually using include())

2. it is in the wrong place.

In CI 2.0 MY_Controller should be in application/core. In previous version it should be in application/library

If classes stored  in a session you must define your class before the call to session start().

If you have  in configuration session auto_start = 1, you will have to disable that so you can define your classes before starting the session.

Another easiest workaround is to define  __autoload() function before session start(). This way the appropriate classes are loaded when needed and it will solve the error. also you do not need to make any changes in configuration file

query_posts(orderby=meta_value&meta_key=sort_order&order=ASC’);

REMEMBER: if you use this function then you have to assign sort_order custom field to each post. Otherwise posts which do not have sort_order custom field will not be displayed.

the more tag does not work on custom queries like that.

You can set the global $more variable to either 1 or 0 to turn the more functionality on or off. Do this right before your call to the content:

global $more;
$more = 1;
the_content();

0 means turn on
1 means turn off

Joomla 1.5 fresh install was working fine and was able to install and uninstall mods, extensions templates, etc. just fine. After a few days of set up,  modifying my templates and adjusting my Global Settings, I was not able to upload any modules, extensions, templates, etc. and continuously received the ‘Unable to Find Install Package’. This was not a legacy issue.

The Solution:

During my setup, I had enabled my FTP but later turned it off in my Global Settings. However, what I discovered was that my FTP was not actually ‘turning off’. When I would deactivate it, and save my settings, the next time that I logged into my Global Settings, it would be back on. To resolve this, I went directly into my configuration.php file and manually adjusted the FTP settings.

var $ftp_enable = ‘0′;
var $ftp_host = ”;
var $ftp_port = ”;
var $ftp_user = ”;
var $ftp_pass = ”;
var $ftp_root = ”;

So, in short — try adjusting your FTP settings directly in your configuration.php file.

I hope this helps someone else!
