When I click on add new article, Joomla shows the page incompletely.
It doesn't even show the form itself completely.
Even now that I have enabled the debug mode, it doesn't show anything. I think that something die()
s the process of outputting the page to the browser.
Please note that I haven't had a bad joomla installation. It was working very well a bit little ago.
I haven't also changed a deep core setting. I think that I have only changed jcomment setting that doesn't look related to the problem.
Add this code in this file root/administrator/components/com_content/content.php
ini_set('display_errors', '1');
error_reporting(E_ALL ^ E_NOTICE);
If no error comes check for die or exit statement with any of the editor which has search functionality.If this also does not work rename the com_content of administrator and upload the fresh one.
let me know if it does not work.
