Hello,
Thank you for contacting our support team today.
With a large number of entries like 17,000, server timeouts can occur during export. To address this, you might consider breaking down the export process into smaller chunks. If your server allows, increasing the PHP time limit and memory limit could also help prevent timeouts.
If you continue to experience issues, please ensure that you are using the latest version of Formidable Forms and check with your hosting provider to see if they can increase the resource limits temporarily for the export process.
Let us know if this helps or if you require further assistance.
Best,
