[Resolved] site library – demo not imported

Hello, I installed generatepress Version: 2.4.1 and gp premium Version: 1.9.1

When I try to import a site from the site library I can’t import images and Elements (header, hooks etc), altough I see the changes in the interface (colors, typography, footer etc) and the plugins associated with the theme are installed.

This happens with any theme.

This is the error returned by my local server with easy php, it seems like I import an empty xml file:

[Mon Dec 09 00:07:05.935883 2019] [php7:warn] [pid 18740:tid 1380] [client 127.0.0.1:51920] PHP Warning: XMLReader::read(): file:/C:/Program%20Files%20(x86)/EasyPHP-Devserver-17/eds-www/xxx/wp-content/uploads/2019/12/content-5.xml:1: parser error : Document is empty in C:\\Program Files (x86)\\EasyPHP-Devserver-17\\eds-www\\xxx\\wp-content\\plugins\\gp-premium\\sites\\libs\\wxr-importer\\WXRImporter.php on line 344, referer: http://127.0.0.1/xxx/wp-admin/themes.php?
