I've encountered a very annoying problem since my updated to 188.8.131.52
The problem is as follows:
- When you're logged in you can't add product to cart / select text or something like that, product page seems broken
- When you're not logged in there is no problem at all
When I go to app/design/frontend/rwd/default/layout/sales.xml and remove sale.reoder.sidebar than the problem is solved. But when I remove this block, customers can't see their order history and when they've purchased a product they don't see the product in the transaction mail. In other words, this isn't actually a solution. It's temporary so that customers who are logged in can still buy products.
