Tue, 08 Mar 2016 10:43:56 +0000

If you get the Invalid login credentials error when using the Magento Connect Manager, you most likely changed your FTP credentials some time ago and the Connect Manager still uses the old credentials.

To get rid of this error, simply open the downloader folder and rename or delete the connect.cfg file. You should be able to access the Connect Manager now.

If the Magento Connect Manager displays the error Invalid login credentials , your FTP credentials may have changed while the Connect Manager still has the old ones stored.

The simplest workaround is to delete or rename the file connect.cfg im downloader in the directory. When you next open the Magento Connect Manager, it will use your current FTP credentials and you should be able to access it again.

Where does Magento Connect Manager store version numbers?

Mex — Mon, 16 Nov 2015 12:00:07 +0000

The Magento Connect Manager’s version numbers are stored in serialized form in the file /downloaderinside the directory (which should be renamed for security reasons) cache.cfg .

You can read that file using the following code:

$contents = file_get_contents('cache.cfg');
$uncompressed = gzuncompress($contents);
$unserializedData = unserialize($uncompressed);

var_dump($unserializedData['channels_by_name']['community']['packages']);
var_dump($unserializedData);

Changing the data stored there is not straightforward. One possible starting point is the code in lib/Mage/Connect/Singleconfig.php inside the save() method.
