can't speak issue directly, know how long worked on debugging problem joomla site wouldn't work paypal, discover joomla takes instance of e-mail address -- embedded in code -- , applies javascript encryption. normally, great. on paypal page, though, means paypal can't determine account (which email address).

i overcame problem when encoded e-mail address html entities (which joomla passes along without javascripting it). google "entity hex encode" (without quotes) , pick 1 of many sites have encoder.

best of luck.
