What is the difference?
Neither spelling changes the role or pronunciation. Adviser follows directly from the verb advise and remains common in edited prose. Advisor is also fully established, especially in North America and in formal job titles such as financial advisor. Preserve the spelling used by an employer, institution, or professional designation.
