```javascript
window.onload=function(){
  
        var tags = document.getElementsByTagName("a");  
  
        for ( var i=0; i<tags.length; i++ ){
  
            tags[i].addEventListener("click", function(event){
  
                event.preventDefault();  
  
                var linkhref = new URL( this.href );  
  
                var params = (new URL(window.location.href)).searchParams;
                var ref = params.get('ref');  
  
                if ( ref !== null ) {
  
                    linkhref.searchParams.set( 'ref', ref );  
  
                }
                window.location = linkhref.href;

```

### Example DateTime Error Message

Source: https://support.yithemes.com/hc/en-us/articles/360013107493-Social-Login-does-not-work

This error message indicates a timezone configuration issue on the server. It requires server-level adjustments or setting the default timezone in your PHP configuration.

```text
DateTime::__construct(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected the timezone 'UTC' for now, but please set date.timezone to select your timezone.

    function yith_wcmv_register_as_a_vendor_form_customizzation(){  
               if( is_account_page() && ! is_user_logged_in() ){  
            $script = "jQuery('#vendor-register').trigger('click');";  
            wp_add_inline_script( 'product-vendors', $script );  
        }

Add this PHP code to your theme's functions.php file to change how variable product prices are displayed. It formats prices from a range to show a starting price, like 'From: $100'. Ensure the YITH Role Based Prices plugin is active.

```php

            $current_filter = current_filter();
            $price_html     = sprintf( __( 'From %s', 'your-text-domain' ), wc_price( $min ) . $suffix );
            if ( 'ywcrbp_variable_regular_price_html' === $current_filter || 'ywcrbp_variable_sale_price_html' === $current_filter ) {
                $rule_price = YITH_Role_Based_Prices_Product()->get_variable_product_rule_price( $product );
                if ( ! empty( $rule_price['rules']['min'] ) ) {
                    $price_html = '<del>' . $price_html . '</del>';
                }
            }
            // Return price if min is equal to max.
            if ( $min === $max ) {
