The diagnostic page tells me to turn off PHP’s register_globals setting. How?
ANSWER:
This depends on the way your server is configured.
On many hosts, you can edit your .htaccess file, and remove the # character from this line:
#php_value register_globals 0
..so it looks like this:
php_value register_globals 0
On some servers, this will cause a 500 Internal Server Error. If this happens, replace the # character at the beginning of that line, and ask your hosting company for advice.
TextDrive customers: register_globals is turned off by default. If it’s turned on, it probably means you have your own php.ini file.
If this is the case, or you operate your own server, you’ll need to add this line to php.ini:
register_globals = Off
