I installed wordpress today and made a post. But when i click on post link under manage>posts to edit the post , i am getting this error:

Warning: ini_set() has been disabled for security reasons in /home/tinyuplo/public_html/tutorialshut.com/wp-includes/pluggable.php on line 1517

Warning: require_once(Text/Diff/Renderer.php) [function.require-once]: failed to open stream: No such file or directory in /home/tinyuplo/public_html/tutorialshut.com/wp-includes/Text/Diff/Renderer/inline.php on line 17
