it appears that:

"Fatal error: RPG_core::init_user(): Attempted to initialise user(s), RPG not initialised with proper variables!

Tthe following variable is missing:

* Genders

To remedy this error, make sure the $specialtemplates and RPG_core::set_cachefields() variables are properly populated.
The error occurred in rpg.php."

I simply needed to add 'rpg_genders' to the end of:

$specialtemplates = array(
'rpg_alignments',
'rpg_categories',
'rpg_clans',
'rpg_classes',
'rpg_elements',
'rpg_items',
'rpg_races',
'rpg_types',
'rpg_genders'
);

and

RPG_core::set_cachefields(array(
'rpg_alignments',
'rpg_categories',
'rpg_clans',
'rpg_classes',
'rpg_elements',
'rpg_items',
'rpg_races',
'rpg_types',
'rpg_genders'
));
