Payment Manager plugin update error

I updated the Payment Manager plugin and got an error page and was unable to reach my admin page or site, the error was:

undefined function geodir_create_page()

The only way I could access my site and info was to comment out the lines listed by the error which contain this:
/* if(!get_option(‘geodir_payment_pages_installed’)) {
geodir_create_page(esc_sql(_x(‘gd-checkout’, ‘page_slug’, ‘geodir_payments’)), ‘geodir_checkout_page’, __(‘GD Checkout’, ‘geodir_payments’), ”);
geodir_create_page(esc_sql(_x(‘gd-invoices’, ‘page_slug’, ‘geodir_payments’)), ‘geodir_invoices_page’, __(‘Manage Invoices’, ‘geodir_payments’), ”);
}*/

I can now access my site but am unsure how this now affects the overall function, can someone give me a hint at how to fix the issue?
