Hi Tuan,
After a server crash I have reconfigured my site with joomla 3.1.1 (it was 2,5) Now when I try to display the payment form page ( {pmform 1} ) i get the following error:
SQL=SELECT id, catid, sectionid FROM bk_content WHERE id=16
where the id=16 page is the article containing the terms and conditions.
please help.
