[TYPO3-shop] sql warnings

[Christina]

Hi list,
some warnings have started to occur at my site, when I view products in 
single view.

(The warning messages have been pasted in at the end of this message)

http://instrulog.cvfront.dk/index.php?id=97&tx_ttproducts_pi1[backPID]=97&tx_ttproducts_pi1[product]=20&cHash=28202efa25

Last time I checked the warning messages weren't there. In between, my 
server has been upgraded to php5.1 and I have made alterations to my 
template and page records related to the tt_news module

Any ideas on how to solve the issues that causes the warning? or just 
how to remove the warnings from the site (as they do not seem to cause 
any errors)?

Thanks in advance,
Christina
