 * It failed for me on 2 careful tries, with an error message:
 * **Warning: Cannot modify header information – headers already sent by […] **
 * Would love to get it to work!

 * Thank you “asposemarketplace”. My server has the latest version of PHP, and I
   did enter the two long key codes.
 * I had to move on to another solution but will keep this in mind. I appreciate
   your responsiveness.
