Hello,
Please update both the plugin https://www.8theme.com/documentation/xstore/plugins/plugins-update/ and the theme at your earliest convenience – https://www.8theme.com/documentation/xstore/theme-installation/theme-update/
If this doesn’t help, we require the following details: FTP host, FTP username, FTP password, FTP port, and FTP encryption type. If you need assistance in creating these credentials, please reach out to your hosting provider who will guide you through the process.
Best regards,
8Theme’s Team
