As per my opinion (as we all know this) advice is a noun and it does not have any plural form and it also can not be used as a verb (not sure about a verb). As per my daily routine I was reading the news on Yahoo and found out an error, so I think, I should clear my doubt here (as I always do).
On Yahoo:
Legend has it that site was blessed by Lord Krishna. On this knowledge, a holy man advices King Jaiswal to build his fort here, where it will remain invisible to his enemies. Named for its golden hue, it is known as Jaisalmer's Sonar Quila or Golden Fort.
It should be:
advices = advises.
Thanks in advance.
