Im getting this same problem, and i think its something to do with out-of-date sidebar.phtml, although im not too sure as im very new to magento, so also need advice on this issue

This does look like an error due to changes in magento theming between 1.4.2.0 & 1.5.0.x

You have a customized theme, right?

Yes, its an off the shelf theme so i can get to grips with using magento. Cant find too much about this issue so any help would be greatly appreciated!, thanks

Well, find what theme was used as a basis for the customized theme (default, modern, blank) and start looking through files in your theme vs default theme used as a basis.

Something changed in 1.5.x theme hooks, which causes your customized theme to fail.  By looking through magento default themes, you will be able to find it.

Im getting the same problem can anyone tell me what’s the solution??
