It doesn’t work for me at all. Tried the whole day and got frustrated.
Permission is good and everything is fine in the wp-content folder and still get the same error “The export file could not be found at /var/www/vhosts/…/httpdocs/wp-content/uploads/rb.wordpress.pages_.xml_.txt. It is likely that this was caused by a permissions problem.“
I notice it amends a .txt to the file name of the .xml file and uploads to the Media folder. If I click the Media link from the left navigation, I see the .xml file converted to .txt.
