Node Processor Mapping - blank page

After updating Feeds module my importer no longer worked. I went into the Feeds Importer Settings and looked through all the tabs. When I got down to the Node Processor section and clicked on Mapping a completely blank page loaded.

Here are my settings:
Attach to content type - use standalone form
Periodic import - off
Import on submission
Fetcher - file upload
Parser - CSV
Default delimiter comma
Using headers
Processor - Node Processor
Bundle - proper content type is selected
Update existing nodes - do not update existing nodes
Text Format - Full HTML
Skip non-existent nodes

My Error Log shows the following error whenever I click on node processor mapping:
