I am having the same issue. THe topic suggested by Yani is not useful to me. I have a javascript error:
<root>/wp-content/plugins/all-in-one-wp-migration/lib/view/assets/javascript/import.min.js?v=7.7&ver=5.2.3:1395
I have increased execution time even to 6000 without success.
Thank you Mandeep for the update, also here the issue is not fixed.
Hi,
Here also WP 5.2.2 just updated the plugin 10 minutes ago, and it stopped working. It duplicates the page but the content is empty. I am using Beaver Builder for content creation.
Kind regards,
