You may encounter such problem when trying to download your backup from the Backups page.
The reason why you cannot download the .wpress file directly from the download button is that your server does not support .wpress file type.
You may need to either;
- add this line AddType application/octet-stream .wpress in to your .htaccess file. Alternatively, contact your hosting provider and get them to add mime type application/octet-stream for you in your web server configuration
- download the .wpress file that you have exported via FTP from wp-content/ai1wm-backups
In case you have taken the above steps and still face the issue, please contact us at firstname.lastname@example.org.
