 * Hi Pankaj!
    I thought I would give yu a heads up. Your plugin is sending: `The
   plugin generated 263 characters of unexpected output during activation. If you
   notice “headers already sent” messages, problems with syndication feeds or other
   issues, try deactivating or removing this plugin.` on activation. If I get some
   time, I’ll try to look into it and suggest a fix. Thanks! [@brianbrown](https://wordpress.org/support/users/brianbrown/)

 * The underlying warning is:
    Notice: Trying to access array offset on value of
   type null in /home/abilicom/public_html/whitehouse.gov/wp-content/plugins/wordpress-
   ping-optimizer/cbnet-ping-optimizer.php on line 257
