php.ini is a global setting you probably don't have access to however you should be able to edit the .htaccess file in your drupal directory. To add a php.ini setting into the .htaccess file add a line like this: php_flag setting value For example in the php.ini file you might have a line like "register_globals = off" which in a .htaccess file would look like "php_flag register_globals off". What you probably want to add is this: php_flag mbstring.http_input auto I'm not sure what the error you're getting means so you might need to look up the correct value from somewhere else. Good luck!

I just installed drupal 5.1 on a web hosting provider. When I try to run install.php, I get the error: Incompatible environment The following error must be resolved before you can continue the installation process: 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 <http://www.php.net/mbstring> for more information. (Currently using Unicode library Error) It is unclear what I'm supposed to do to fix this. I don't see any php.ini string anywhere in my site directory tree. I'm assuming this is some system global config file (which I don't have access to). -- roy@panix.com
