Can not add item to cart - is null or not an object

[it@isa-arbor.com]

We are running AC 7.0.2. The store has performed well since last fall, but today we hit an error. Customers can not add a product to their cart from the product detail/description page. No errors show up in the store log, but three errors are visible in Internet Explorer.

My hunch is something is corrupt or missing in the database or a file on the site is corrupt. We need help resolving this issue.

This must have been broken unoticed for a few weeks. Several weeks ago we commented out

[[ConLib:ProductTellAFriend]]

From the product bar like this

<!--[[ConLib:ProductTellAFriend]]-->

That broke the page and created the errors. Readding this line or completely deleting it solved the problem. We're good to go.

sounds good. I thought its something wrong with user agent.
