Lesley,
the import plugin finally ended up displaying this error info :
“Unable to import
Unable to open file for reading.”
Does it tell you something?
I verified, and my file is readable.
Hi Lesley!
Unfortunately, i cannot deactivate the Must-Use plugins on my WordPress.
I changed my PHP version on my localhost to match with the one on the distant server and I still have the migration process stuck at “Done preparing blogs.”.
I guess it comes indeed from the Must-Use plugins as suggested by your error.log
But i will try one last import with all the other plugins deactivated, just to be sure.
I will tell you back.
The WP_DEBUG set to true reveals a few warning related to the Must-Use plugins anyway.
Thank you for your help.
Manuel
