Short answer

An attachment upload can time out when the request exceeds the configured PHP execution time. The default upload timeout is 30 seconds, controlled by max_execution_time in php.ini.

In this article

Review the timeout setting

  1. Locate the php.ini file for the PHP environment used by Sanplex.
  2. Find max_execution_time.
  3. Increase the value only when the existing limit prevents a legitimate upload.
  4. Restart the relevant web service and retry the attachment.

Check the upload as a whole

  • Confirm that the file fits the configured attachment-size limits.
  • Check the network connection between the client and the Sanplex server.
  • Review web-server and PHP logs if the upload still fails.

For the Windows ZBox installer, edit Sanplex\\etc\\php\\php.ini.

Important: Keep the timeout below 60 seconds. Sanplex generally does not recommend increasing max_execution_time above 60 seconds; for very large files, use a shared drive and link to the file instead.
