Captcha images not working on websites !!!!

               
This issue is due to the absence of a module called TTF (free type support for php ). It depends on how your version of  php was compiled. Please check your version of GD and PHP, Since php.net suggests that you need atleast 1.8 version for this support.

Fix :

           1 .Login to WHM

           2. In home select "Software" then "EasyApache (Apache Update)"  then select "Previously Saved Config" then in the bottom of the page click the button "Start customization based on the profile" then go to Exhaustive options by completing the previous steps then make sure checkboxe for "TTF" are checked. Once they are checked then initiate Build process.
