The functions ti_exclude_js() and ti_exclude_inline_js() are declared in both Google reviews AND in Tripadvisor reviews plugins, without checking if they already exist !
You have this error if you activated both plugins. The solution I found was to edit the /wp-content/plugins/review-widgets-for-tripadvisor/review-widgets-for-tripadvisor.php file, comment the two functions to remove the error, open the site administration and disable the Tripadvisor reviews plugin.
This will work until Trustindex fixes the error and updates the plugins…
