I cannot modify entity values I have installed the Views Bulk Operations module and am looking to use it to mass edit my content. However, when I select a few nodes to edit and select Modify Entity Values and click Execute, I get taken to a page that simply says, "The website encountered an unexpected error. Please try again later."

Unfortunately, my server logs and Drupal logs come up empty as to what error may have occurred. 

Additionally, it seems like when I select Modify Entity Values, I should see an option for what entity value I am looking to modify but I am never presented with that option.

As an alternative, I found a guide that demonstrates how to replicate this behavior with Rules components but I have not yet been able to figure out how to make this work with taxonomy terms. 

I would prefer however, to simply get the Views Bulk Operations to work as I would expect.
I finally managed to get this working. Under show available tokens, I previously had selected -- All --.

I have since changed this to be just the fields that I'm interested in having edited and it works as expected now.

My theory is that I have a lot of content types with a lot of fields and it was hitting some sort of memory error. However, I never saw an error reported.
