I am getting an error when trying to export either an article or an issue

I am using OJS 3.3.0.13 and I am getting an error on the page that says Wrong filter configuration [issue=>native-xml]: 0 occurrences. Should be only one. I checked my error_log file and there’s nothing that was logged for the time I tried doing the process.

Here’s what I’m trying to do:

  1. In the Admin site, go to Website->Plugins
  2. Under Import/Export Plugins, open Native XML Plugin
  3. Click on Import/Export Data
  4. Click on Export Issues
  5. Select 1 issue
  6. Click Export Issues

It is such a broad error that I have no idea what could be wrong, I even tried with a single article and I get the exact same message.
