Finally, I found something useful on Joomla! Discussion Forums.
To solve this issue, simply change the following configuration in your php.ini file.
error_reporting = E_ALL | E_STRICTto
error_reporting = E_ALL & ~E_STRICT
display_errors = Onto
display_errors = Off
Remember to restart your Apache server after the changes. You should be able to view to Joomla! homepage now.
