Error When Saving Candidate Record

Error When Saving Candidate Record

I receive an error (attachment: Zoho-Error Page) when editing and saving data entered into custom fields on the Candidates page. From the candidate list, If select "edit" on the left side of the candidate page and enter the desired information into a custom field (i.e. Certifications-Other), I receive the error when I try to save the candidate record. If I open the Candidate's record to view the content, then select "edit" by the field I desire to update (i.e. Certifications-Other), I can enter the information and save it. Please advise.
