Magento left side not working
This is a common problem but it has a simple solution.
You may find that the left side is not working for particular categories.
Your website left side is not working becouse your category is not an anchor. This is a setting from admin.
1). To solve that go into magento admin area.
2). Go to catalog->manage categories
3). Choose some category and click on “Display settings” tab. Select Is Anchor to YES
In this case magento left side is working, but is not displayed.
Not sure why this is happening but it may help you.Try it.
