Hi,
How did you update the theme?
Please update the theme with following step.
1. Check php version of your website. It should be greater than 7.2. If not, please update it in your hosting server.
2. Download latest version from themeforest and extract it.
3. Replace travelo theme with latest version in your website using ftp.
4. activate another theme and activate travelo theme again in admin
5. Install/update required plugins in Travelo -> Tools menu in admin.
And i can see your support license was expired. Please purchase another one to get our support.
Regards, C-Themes
