FOX fixed a glitch yesterday on its “American Idol” Web site that may have been tapping into fans’ wallets.

After some “Idol” viewers complained that they believed their text-message votes were getting tossed, Fox clarified a section of its FAQ about the show.

Only text message votes cast on Cingular cell phones count – other text message votes are disregarded, fan blogs complained yesterday. After a call from The Post, the top of the FAQ section was updated to make it clear that Cingular phones are the only way to cast a textmessage vote.

A Fox spokeswoman said that “Idol” host Ryan Seacrest frequently mentions on the show that Cingular is the only

acceptable way to text message in a vote.
