Magento Community Connect: Not valid config.ini file

Question

We're running Magento Community.

When I navigate to System > Magento Connect > Magento Connect Manager, I got a blank screen with a single message:

Not valid config.ini file.

If I open /downloader/config.ini with Notepad or Notepad++, I see lots of black NULLs.

How can I fix this problem ?

Answer 1

I replaced the contents of /download/config.ini with:

root_channel=community

and the Magento Connect Manager opened successfully.

Perhaps the file got corrupted on upload/download.
