Thanks for reporting this issue and for all the logs. Usually this occurs when exporting a site that is already having configuration problems (by itself). For example, exporting a site without an active theme activated in dB but deleted, invalid site url, etc. Based on the log provided, it shows it indeed fails on footprint validation.

The current version 1.0.3 does not yet include a detailed logging to see the footprint data in details. We will add it on the future version. To understand the issue, we want to know what part of the footprint is missing or invalid. Can you please do the steps below:

1. Download this Prime Mover footprint logging plugin.
2. Log-in as administrator go to Plugins -> Add New and upload that plugin zip: prime-mover-footprint-log.zip.
3. Activate the plugin named as: Prime Mover Footprint Log
4. Enable all logs as what you have done first time when you report this issue
5. Now the footprint log is enabled, re-generate the export (to reproduce the error) so it will re-generate another set of logs (now including footprint which we need to analyze).
6. Update the log in your pastebin with the latest log containing footprint data: https://pastebin.com/VrN7PyfM

You will know that the footprint data is logged when it contains “Custom log for site footprint data” in the log. Let me know if this is added so I’ll re-check the log for analysis. Thank you !

OK I found the issue after checking the updated logs. Prime Mover checks the theme version used when exporting so it can be compared during restoration process to check for theme differences. It’s included as required footprint of the source site. It is why without this, it returns invalid system footprint error.

The exporting site is using a child theme Divi-child that does not include a theme version.

To fix the error, can you please add a version to your child (Divi-child)? This is done in the child theme style.css file.

For example from: (before)

/*
Theme Name:   Divi Child Theme
Theme URI:    http://xxx.com
Description:  Child theme, based on Divi
Author:       xxx xxx
Author URI:   http://xxx.xxx
Template:     Divi
*/

@import url("../Divi/style.css");

TO: (after -this is the right way – including theme version)

/*
Theme Name:   Divi Child Theme
Theme URI:    http://xxx.com
Description:  Child theme, based on Divi
Version:      1.0.0
Author:       xxx xxx
Author URI:   http://xxx.xxx
Template:     Divi
*/

@import url("../Divi/style.css");

Try this one and the export error should be resolved. Let me know how it goes 🙂

Thank you for confirming the fix works. The stalling on export and import is a known issue with version 1.0.3 that is caused by web server timeouts. We are on the process of adding an improvement to this one and will be included in the next release version 1.0.4.

If you are affected again with this issue, please create a separate ticket. And we will provide you with a beta version to test. Cheers.
