Thanks for your help. I said I would follow up on the conversation with 2046 here:
I have not gotten to the bottom of this problem and the situation now is that I have Easy installed and the website is working correctly. However, I cannot turn on my other plugin W3 Total Cache, and this is a problem. I also have a third plugin called WordPress Page Widgets that has allowed me to choose what widgets get shown for each category. I think there is a compatibility issue involving some combination of these three plugins. W3 Total Cache is likely not where the problem is originating but I can't turn it on at this time without major issues because it is not liking something. Could there be compatibility issues between Easy and W3 Total Cache. Or between Easy and WordPress Page Widgets?
I have emailed W3 Total Cache to see if they can fix this issue too.
