I went to System > Manage store
to delete the view,
Actually I deleted only one view which I created when I tested the magento system.
right now ‘Default Store View’ still be there, but the one I deleted already gone..
so I think this may cause the problem
for the block
On product detail layout, I just added a block right under the product description tab for showing other product pictures so I created media2.phtml in the same folder as media.phtml and link it on
catalog.xml …Did I done the right solution?
Before I deleted that view, It shows other product pictures exactly what i need, but after that that view, all other product pictures disappear…
