- I'm officially tired of watching out for uses of PHP 5.3+ in code that could get run in the installer. From now on, the test will be done on index.php (it's fast enough not to bother), and will just return an error message in English, because... Well, if you don't speak a word of English and don't know what PHP is, you should let someone else handle your forum's administration... (index.php, install.php, Install.english.php)
