Broken Excel export

[smnedelko]

What happened?

When exporting submissions to Excel format, the next error occurs:

yii\base\ErrorException: ob_end_clean(): Failed to delete buffer. No buffer to delete in /app/vendor/solspace/craft-freeform/packages/plugin/src/Library/Export/ExportExcel.php:42

In the plugin/src/Library/Export/ExportExcel.php, the buffer is read using ob_get_clean function:

$writer->save('php://output');

$content = ob_get_clean();

ob_end_clean();

To fix it, the ob_get_clean should be replaced with the ob_get_contents function.

How can we reproduce this?

1. Create a form with a couple of fields
2. Go to the form submissions page
3. Make a Quick export in Excel format

Sorry for the delay and the trouble @smnedelko,

I can't duplicate this on my end, but I will have a developer check into it. 🙂

This should now be resolved in Freeform 5.7.2+ 🙂
