None of the suggested fixes worked for me. Too bad. This plugin worked great for a long time. Will have to look for a substitute.
I am suddenly having this same problem. lukehill, did you ever resolve it?
I am having a similar problem exporting to Excel Internet Query. I’m thinking that the problem is that I have wordpress installed in a subdirectory. @cruxwireweb, do you also have wordpress installed in a subdirectory?
