I just opened a free hosting at freehostia.com and installed drupal thru their Elefante script installer. The installation was fast. I was able to access my site but when I logged-in as admin, there are errors at the 'Status Report'. The errors are as follows:
1. HTTP request status Fails
Your system or network configuration does not allow Drupal to access web pages, resulting in reduced functionality. This could be due to your webserver configuration or PHP settings, and should be resolved in order to download information about available updates, fetch aggregator feeds, sign in via OpenID, or use other network-dependent services.
2. PHP register globals Enabled ('1')
register_globals is enabled. Drupal requires this configuration directive to be disabled. Your site may not be secure when register_globals is enabled. The PHP manual has instructions for how to change configuration settings.
3. Unicode library Error
Multibyte string input conversion in PHP is active and must be disabled. Check the php.ini mbstring.http_input setting. Please refer to the PHP mbstring documentation for more information.
I tried reading the links (about the PHP) but I can't seem to understand it and was not able to locate what are the necessary steps to correct these errors. Are these errors really critical? What are the steps to correct these errors?
