I've been having the problem for about a week and I cannot find a work around. I can't seem to install extensions at all.
I am using Magento 188.8.131.52 and when I go to Magento connect I get a 404 error. I have tried CHMOD downloader & downloader/index.php to 644 but still get 404.
Is there a workaround or a way to manually install extensions? When I have tried via FTP it tries to overwrite existing files which it shouldn't.
