CMS Made Simple Forums

Hello ,
I upgraded CMS Made simple from 1.8.2 to 1.9.1 and the page turns to tree like menus and and getting the below error and the bottom of the page.
(Fatal error: Maximum execution time of 40 seconds exceeded in /mounted-storage/home119b/sub005/sc67069-HMQQ/www/made/lib/classes/class.cms_tree.php on line 305)

What should i do to correct this?
Thanks in advance

Most likely it is something to do with PHP execution, either change it in your php.ini or .htaccess or talk to your host...

Problem Solved.
Thanks to Dr CSS
