Howdy,

I recently migrated a site, but having issues when I enable error logging (need it for other issue)  
.

On the page with a gravity form I have this issue:

`str_replace(): Passing null to parameter #2 ($replace) of type array|string is deprecated (View: /var/www/site/wp-content/themes/test-theme/theme/partials/pagebuilder.blade.php) (View: /var/www/site/wp-content/themes/test-theme/theme/partials/pagebuilder.blade.php)`

```auto
/var/www/site/wp-content/plugins/gravityforms/includes/fields/class-gf-field-list.php

                        if ( is_array( $choice ) ) {
                            $choice_value = $choice['value'];
                            $choice_text = $choice['text'];
                            $choice_selected = array_key_exists( 'isSelected', $choice ) ? $choice['isSelected'] : false;
                        } else {
                            $choice_value = $choice;
                            $choice_text = $choice;
                            $choice_selected = false;
                        }
                        $is_selected = empty( $value ) ? $choice_selected : $choice_value == $value;
                        $selected = $is_selected ? "selected='selected'" : '';
                        $input .= "<option value='" . esc_attr( $choice_value ) . "' {$selected}>" . esc_html( $choice_text ) . '</option>';
                    }
                    $input .= '</select>';
     
                    break;
     
                default :
                    // a11y: inputs without a label must have the aria-label attribute set.
                    $input = "<input {$invalid_attribute} {$required_attribute} {$aria_describedby} aria-label='" . esc_attr( str_replace( '{0}', $row, $aria_label_template ) ) . "' data-aria-label-template='" . esc_attr( $aria_label_template ) . "' type='text' name='input_{$this->id}[]' value='" . esc_attr( $value ) . "' {$tabindex} {$disabled} />";
                    break;
            }

```

the section it’s highlighting is:

`$input = "<input {$invalid_attribute} {$required_attribute} {$aria_describedby} aria-label='" . esc_attr( str_replace( '{0}', $row, $aria_label_template ) ) . "' data-aria-label-template='" . esc_attr( $aria_label_template ) . "' type='text' name='input_{$this->id}[]' value='" . esc_attr( $value ) . "' {$tabindex} {$disabled} />";`

Any ideas how I can fix it?

I’m running Gravity Forms: 2.7.6

Thanks!

There was another error:

/var/www/site/wp-content/plugins/gravityforms/includes/addon/class-gf-addon.php

```auto
$block_settings = isset( $all_block_settings[$form['id'] ][$form['page_instance'] ] ) ? $all_block_settings[$form['id'] ][$form['page_instance'] ] : array();

```

With help of the oh mighty lord ChatGPT this helped:

```auto
$page_instance = isset($form['page_instance']) ? $form['page_instance'] : 0;
$block_settings = isset($all_block_settings[$form['id']][$page_instance]) ? $all_block_settings[$form['id']][$page_instance] : array();

```

^^^ dont know if this is correct fix, just had to push through to another error.
