Hello,
Were all the plugins installed successfully? In case if automatic plugin installation fails, you can install them manually via your Dashboard: Plugins > Add New > Upload Plugin > Browse plugins archives. Or via FTP, by uploading and extracting the plugin zip files into wp-content/plugins folder – https://www.8theme.com/download-plugins/
Try to install demo content from XStore > Import Demos or provide temporary admin panel access and we’ll help you.
Regards
