 * Hi
    Every time my ‘add a new porfolio item’ page loads I get this warning.
 * Warning: in_array() [function.in-array]: Wrong datatype for second argument in/
   home/content/88/6940688/html/wordpress1/wp-includes/theme.php on line 1682
 * It then prevents me from adding any media to my new page.
    My theme is Portfolio
   Press version 1.5. I know there is a 1.8 upgrade but I have edited the theme 
   to extend porfolio items and removed date stamps so I don’t want to have to recode
   these parts.
 * FYI this error has only just happened along time after the before mentioned tweaks
   we made.
 * Any info you can give me would be most appreciated.
 * Thanks in advance

 * The error simply means you’re not passing an array as the second argument. Take
   a look at the documentation to see the order of the arguments.
 * Give your code to provide you a good solution.

 * Many thanks for you advice chaturaka.
    I decided to upgrade the theme to solve
   this problem. Now I am just trying to figure out how to create a child theme 
   in my function.php and add a filter???
