Good day,

I keep getting these errors with the bbcode in the forum example in chapter 16:

Warning: preg_replace(): Unknown modifier 'g' in C:\Path tosite\..\functions.php on line 341

Warning: preg_replace(): Unknown modifier ']' in C:\Path tosite\..\functions.php on line 341

Warning: preg_replace(): Unknown modifier 'b' in C:\Path tosite\..\functions.php on line 341

Warning: preg_replace(): Unknown modifier ']' in C:\Path tosite\..\functions.php on line 341

Warning: preg_replace(): Unknown modifier 'r' in C:\Path tosite\..\functions.php on line 341

Warning: preg_replace(): Compilation failed: unmatched parentheses at offset 12 in C:\Path tosite\..\functions.php on line 341

I am using PHP 4 because of compatibility issues still related with old sites of mine and PHP5.
If this is an issue related to PHP4, anyone have any idea on how I might be able to change the code to make it work?
