Q: I’m getting certificate errors when I try to make a purchase or donation.
A: This may be caused by old information stored in your web browser. Try clearing the cache (usually found in your browser’s settings), then make your purchase again.
If this doesn’t fix the problem, check that your computer’s date/time are current, or try lowering your browser’s security settings.
