I think I got a scrwed up version (?)
The older version worked, but instead of for example parsing {AUTHOR}, it would just parse the word, so if I wanted to include the word author and not have it parsed, it would parse it anyway.
This is resolved by opening class.fasttemplate.php3
Going to line 199 and changing this
$template = ereg_replace("{$key}","$val","$template");
to this
$template = ereg_replace("{"."$key"."}","$val","$template");
Now you have to have {'s around the name to have it parsed by fasttemplate.
