I am currently trying to install Magento 1.9.1.0 Downloader release. However when I get to the download part of the installation the following message appears at the top of the page:
Warning: include_once(Mage.php): failed to open stream: No such file or directory in /home/drainage/public_html/magento/downloader/lib/Mage/Autoload/Simple.php on line 49
Warning: include_once(): Failed opening 'Mage.php' for inclusion (include_path='.:/opt/php55/lib/php') in /home/drainage/public_html/magento/downloader/lib/Mage/Autoload/Simple.php on line 49
It proceeds with the download process but then gives me this message and will not allow me to continue. Can you please help?
"There was a problem during downloading of Magento packages. Please check the output frame for errors information and refresh the page to retry again."
