Message could not be sent. Mailer Error: Invalid address: (to):

it gives errors of trouble shooting of phpmailer library in live hosting server

those directories from downloading the phpmailer and where to place mailer.php were clashing especially when executing the code as is....I figured a work around and now its working. Thanks
