iam a normal user and not a coder. i was using an older version of Magento i think 1.7.xx and tried updating it to the latest version 1.9.1, tried performing this step via Magento connect, but the update was interrupted, stating System TImeout, and since then iam getting an ERROR:
Cannot send headers; headers already sent in /home/newspape/public_html/app/Mage.php, line 676
and when i try visiting my site via www.mywensite/downloader iam getting an page: Index of /downloader.
Please help me reactify this issue and update magento to the latest version
You maybe best uploading all the current 1.9 files via FTP as your connect stopped half way.
