Resolved Problems exporting data from virtuemart and custom fields

Hello,

no see the error

Hello,

You are mixing up 2 different things. Your first issue is using the browser to export and your second issue is the cron export. Tell me:

1. Can you export via the browser?
   
2. Is the export file created using the cron? It looks like Plesk doesn't like the output to screen.
   

now if I try with the browser the server times out because it is a very large file.
There are many products with tons of custom fields
What can I do?

I came back and created the file only which has no extension, I tried to rename it to csv but it does not open it
Where am I wrong?

To check if the export works you can set the export to get only a few records. To do that go to the export template settings and on File tab set From record to 1 and To record to 100, save the template and run the export.

Check if you have set Filename for exported file field on File tab with extension. That would be a reason you are getting a file without extension. If you still have issues post the debug log of the export. To get the debug log check How to get debug information? document.
