Thanks for your help
​
Store file doesn't work, i have an error
Error saving the csv file.
​
The path exists, directory in 777
{path:front}/uploads/enrollments/enrollments_export.csv
​
Do you have any idea ?
Regards

Dies it download properly?

yes

Shouldn't it be 755? 777 is a bit too permissive right?
​
But I don't know what the deal is sorry. Just tested it and it works for me, so probably just make sure the folders actually exist.
