Hi Bob,
Thanks for reporting this.
Please first check the PHP version on your hosting account. For the current Travel Kit template/Joomla 5 setup, PHP 8.3 is recommended, and the Travel Kit documentation lists PHP 8.2, 8.3, or 8.4 as supported.
Please change your server PHP version to PHP 8.3 from your hosting control panel (cPanel/Plesk), then clear the Joomla cache and check the website again.
You can also review the Travel Kit technical requirements here:
Travel Kit – Technical Requirements
If the issue remains after upgrading to PHP 8.3, please let us know and provide the error message/screenshot so we can investigate further.
Thanks
