Online LVN to RN classes in Cali

Does anyone know if there are any LVN to RN classes available in California?? If you go to the websites that are advertised on this site and choose the state "California" an error message pops up with something about these classes are not available to this state and to please choose another?? Is there not a nursing shortage, especially with RN's?? Wouldn't it be more beneficial to allow for their education (especially with someone who is already a fellow nurse?) to be gotten swiftly in order to fill this shortage??
