[TYPO3-english] Problem with tt_products

[Peter Kühnlein]

Dear Colleagues,

I'm just setting up an e-shop with tt_products. Everything works fine, 
except for one step in the process of ordering. When I click on 
"Finalize" after entering and reviewing the data, I receive an error message

"Fatal error: Call to undefined method 
tx_div2007_alpha5::fixImageCodeAbsRefPrefix() in 
/www/htdocs/w00e5763/typo3conf/ext/tt_products/view/class.tx_ttproducts_basket_view.php 
on line 624"

The record for the order is added to the page containing the plugin with 
code "Finalize" though.

My Typo3 version is 4.5.4, I'm using tt_products 2.7.2 and div2007 
v0.6.1. Does anyone have an idea what might be going wrong here?

Any help is greatly appreciated
Thanks - Peter
