I am having a 0 bytes data export issue similar to this thread from yesterday that is now closed (otherwise I'd post there!):
I am using Gravity Forms v1.6.5, WordPress v3.4.1 with Twenty eleven theme.
I have a form that shows 70+ entries correctly in the Entries screen. But when I go to use the Export function to output those entries as a .csv, I seem to get a 0 bytes file no matter what I do.
I have tried selecting only a few fields to export.
I have tried limiting the date range.
I have tried not limiting the date range.
I have tried selecting all fields.
I have tried deactivating all other plug-ins except Gravity Forms.
I am already using the default Twenty eleven theme.
The Export function worked correctly for this form as recently as yesterday.
The Export function is also still working correctly for my other forms today -- it's just for this one form ID that I can no longer get to export data.
Any ideas to help me pinpoint where the problem might be hiding would be much appreciated.
