OK, could I ask you then to please set up an example with WPForms using notifications on one of our test servers so that I can investigate the problem.

You can use this link to log in to the back end of the site: hidden link

Could you please activate PHP 8.0

That's not an option on the sandbox sites, but I don't see any changes in PHP 8 that would result in the issue (wrong second parameter type) being handled differently.

If for some reason the error isn't triggered with the sandbox PHP version I can copy the site to a local server for testing where I can set it up with PHP 8.

The link to the bug mention PHP8 issue:
https://wpml.org/errata/wpforms-php-8x-issue-submitting-a-form-with-checkboxes-fields/
I guess it could be related to PHP version

To try, you need to use a link with parameters like this one (some hidden fields are filled with parameters).

After printing some variable in my error_log, it looks like this happens with fields like "Likert Scale" (radio buttons) from the WPFORMS ADDON "Survey & Polls" with plugin "WPForms Multilingual" activated on PHP 8+.

It looks like the filter on line 632 of the file /wp-content/plugins/wpforms/includes/emails/class-emails.php stop to work when the plugin parse a field of type "Likert Scale" with WPFORMS MULTILINGUAL plugin active.

$field_item = str_replace(
    '{field_value}',
    apply_filters(
        'wpforms_html_field_value',
        $field_val,
        isset( $this->fields[ $field_id ] ) ? $this->fields[ $field_id ] : $field,
        $this->form_data,
        'email-html'
    ),
    $field_item
);

I have a copy of your demo installed locally and I'm looking at it now.

OK, I have identified where in the code base the issue occurs, and I've gathered together all of the details and shared them with our compatibility team who are responsible for the WPForms Multilingual plugin.

As soon as I get some feedback from them, I'll let you know.
