[Typo3-shop] Problem with tt_products 2.2.4

[Chris Wittmann [SwiftLizard]]

Hi Folks,

i got a little problem to get my shop running with the latest 
tt_products version.

I have set
plugin.tt_products.orderEmail_htmlmail = 1
plugin.tt_products.orderEmail_to = chris at swift-lizard.com
plugin.tt_products.orderEmail_from = chris at swift-lizard.com
,
when i did so i get the following Error message and no
email was send:

Warning:
parse_url(http:///index.php?id=40&type=0&tracking=order_17-30d031): 
Unable to parse url in 
/home/neugebauer-beck/html/typo3_src-3.8.0/t3lib/class.t3lib_htmlmail.php 
on line 1243

Warning  Cannot modify header information - headers already sent by

in 
/home/neugebauer-beck/html/typo3_src-3.8.0/typo3/sysext/cms/tslib/class.tslib_fe.php 
on line 2612


If I set plugin.tt_products.orderEmail_htmlmail = 0 neither an 
errormessage is displayed nor an email is sent to my account.


Has anyone ideas what the problem could be ?


thanks for the help
