Regards, Ismael September 7, 2012 at 3:17 pm #90057 finkelstein2004Participant Sure. I had to change all the file permissions to 775 and change the PHP version on my host to PHP5. It was originally on PHP4. The theme is designed for PHP5 and WordPress version 3. September 8, 2012 at 4:36 am #90058 IsmaelModerator Hey, Thanks for the tip.
