2 problems

[Crusty]

thumbnails are now completely broken even when dynamic resizing is switched off.

prices are now displayed in the shop to the frontend user without tax (this is a legal requirement for Australian shops)

[Crusty]

prices are now displayed with tax, the upgrade wiped the vendor information.

however now i have another problem - all of my content items will not display.

i get these errors:

Warning: Attempt to assign property of non-object in /home/avclarit/public_html/components/com_content/content.html.php on line 918

Warning: Attempt to assign property of non-object in /home/avclarit/public_html/components/com_content/content.html.php on line 924

exactly what was changed to cause this problem?

i'm using joomla 1.0.15 and vm 1.1
