“Cannot modify header information - headers already sent by (output started at”

If you get a error saying so in wordpress after installing a plugin, the pretty simple reason could be there might be blanks spaces or enters after ?> in your plugin File. Simply remove those blank spaces (or enters) and this warning /Error should go off.

      numerous occations ive found this error. It should be always after the ?> ending in php. To spot the location it’s easy, just follow to the line number as per the error and you can easily find that its after ?>. So just delete those blanks spaces and you are done. No more Headers already sent error.
