After a few years I installed Xerte again to start building. I have created a local page and want to export it to import onto my website. After exporting, the test file (xxx_deploymentTEST.zip) appears to be empty. Other pages also seem to be exported, I don't get any error messages or anything like that, but the export zips are empty. Even after a new installation, the export produces an empty file.
But the installation on my website does make good exports.
Does anyone have an idea what could be going on and how to solve the problem?
