Just so you all know I got it to work!!!!  I did all the rebuild and blah blah blah and nothing helped.  It was only happening to one of my clients!  When I went into the client the boxes were marked to recieve online payments via credit card and check but it still wasn't working.

I went into the invoice and at the bottom left side there is a statement above the memo that says "Your customer can't pay this invoice online".  I clicked turn on and selected the credit and bank.  I saved and resent email and it worked!!!!!

If this was a memorized transaction make sure you all memorize it again and write over what was in the memorized transaction list.

No clue why this randomly happened??  Especially since in the customer info it was setup to make online payments.  I guess if an invoice is marked to NOT receive e payments it overrides what's in the customer info settings?

I hope this all helps everyone!  Happy payroll quarterly week everyone! :)
