Assuming you have your original citation copy, look at the appearance date on that copy. That's the date by which you must appear to post bail in your case OR make your request for Trial By Written Declaration, which allows you to contest your case by mail. If you are able to contact the court by email or phone, you can request an extension of that date, IF your case gets into the database. Regardless of website problems or your distance from the court, you are required by California Law to do one of those two things.

If you don't do one of the two things above, you will have further legal complications, the least of which will be a 300 dollar civil penalty added to your fine amount. If you do appear in the court and your case is still not in the database, you should take a written note with you to the clerk's window and get this stamped as proof of your appearance.
