Report Exports are all blank

What version of PHP are you using? Do you see any errors in your error log?

Having the same issue but only on one site. No errors in the logs. Was on PHP 5.2, upgraded it to 5.4.23. Have it working perfectly on several other sites, but this one reports all exporting as blank files. I’m thinking it’s a compatibility or permissioning issue with another plugin, but not sure which one. Any insights appreciated.

UPDATE: The actual file is correctly inserted into the /wp-content/exports folder. So everything appears to be working except for the actual download action.

UPDATE AGAIN: So there was something about the NextGen Gallery Plugin version 2.0.17 (https://www.nextgen-gallery.com/) that was breaking the download action for Exports and Reports. I upgraded NextGen Gallery to the latest version 2.0.40 and everything works fine now. No idea what is different between the two that caused the problem.

@jchaspel may want to look into your other plugins to see if any of them are breaking Exports and Reports.
