 * Hi,
    I was not able to get into my WP-admin login page as it was giving me a 
   fatal error. My site is [http://www.greenchemicalsblog.com](http://www.greenchemicalsblog.com).
   When BlueHost worked on it, they had to deactivate Jetpack. When I tried to activate
   it again, I get error message “Plugin could not be activated because it triggered
   a fatal error.”
 * I am on BlueHost using Morning After theme, running PHP 5.2.17.

 * I’m sorry to hear you’ve run into issues!
 * Could you add the following to your site’s wp-config.php file?
 *     ```
       define( 'WP_DEBUG', true );
   
       if ( WP_DEBUG ) {
   
               @error_reporting( E_ALL );
               @ini_set( 'log_errors', true );
               @ini_set( 'log_errors_max_len', '0' );
   
               define( 'WP_DEBUG_LOG', true );
               define( 'WP_DEBUG_DISPLAY', false );
               define( 'CONCATENATE_SCRIPTS', false );
               define( 'SAVEQUERIES', true );
   
       }
       ```
   
 * Your `wp-config.php` file may already include a line that says “define(‘WP_DEBUG’,
   false);”. You can remove it, and replace it by the code above.
 * Once you’ve done so, try to activate the Jetpack plugin again and then check 
   the `wp-content/debug.log` file for errors. You can paste the results here. You
   can then replace `define('WP_DEBUG', true);` by `define('WP_DEBUG', false);` 
   in the code above.
 * Thanks!
