I can not import the demo. It shows that it has been succeeded but it only installed the plugins.
I have an error log like this:
” Got error ‘PHP message: PHP Warning: Invalid argument supplied for foreach() in /usr/local/www/sites/enigma-restobar.pl/wp-content/plugins/advanced-import/admin/class-advanced-import-admin.php on line 1030’, referer: https://enigma-restobar.pl/wp-admin/themes.php?page=advanced-import”
Do you have any clue what can be the problem?
