how's it going.
I'm trying to export customers as a CSV file via System > Import/Export > Export, and I just get a blank page as a result.
I select Entity Type of Customers and Export File Format of CSV. When the Entity Attributes table appears I leave it blank and click the Continue button. After a few seconds, blank page. I have made sure that the page has finished loading.
According to Chrome's Developer Tools, Network tab, I'm getting a Server Error (HTTP 500) response but no content. So I'm thinking fatal PHP runtime error. But I don't really know where to go from here. I'm struggling to find the code that's supposed to be running, what with admin controllers being a bit different from frontend ones. And for once, Google's come up empty.
I'm using Magento CE 18.104.22.168 recently upgraded from 22.214.171.124. So have any of you lovely people come across this before and/or know what to do about it?
