I installed v150 out of the box no plugins. When i add a category an empty record is added to the database. When i try to add a product the same problem occurs but an error message is provided. I have cleared browser data including the cache and tried FireFox and Chrome and the problem still exists.

I need to get a good installation of 1.5.0 to run with the Auction plugin.
