Warning: Invalid argument supplied for foreach() in?/home/customer/www/travellingmunchie.com/public_html/wp-content/themes/isla/inc/custom-controls/custom-controls.php?on line?496

I am brand new to setting up my own websites and have no idea where to go or what to do to fix this. I read up on it online and it said something about changing the foreach () but I do not have a clue how to get there. Someone please help!

Warning: Invalid argument supplied for foreach() in /www/wwwroot/mydomain.com/wp-content/plugins/advanced-iframe/advanced-iframe.php on line 66

Not sure why?

if ($options['action'] === 'update' && $options['type'] === 'plugin' ) {
 foreach($options['plugins'] as $each_plugin) { //line 66
 if ($each_plugin==$current_plugin_path_name) {
 $this->saveExternalJsFile(false);
 }
}

Warning: Invalid argument supplied for foreach() in /home/customer/www/finlightened.com/public_html/wp-content/plugins/insert-php/includes/class.execute.snippet.php on line 679

How can this be fixed? Thank you for the help.

Line 679 is this in code below: foreach ( $filters[0] as $filter ) {

	/**
	 * Check conditional execution logic for the snippet
	 *
	 * @param $snippet_id
	 *
	 * @return bool
	 */
	public function checkCondition( $snippet_id ) {
		// Итоговый результат условий
		$result = true;
		// Получаем сохранённые параметры условий
		$filters = get_post_meta( $snippet_id, WINP_Plugin::app()->getPrefix() . 'snippet_filters' );
		// Если условия указаны
		if ( ! ( empty( $filters ) || isset( $filters[0] ) && empty( $filters[0] ) ) ) {
			foreach ( $filters[0] as $filter ) {
				$conditions = $this->getPropertyValue( $filter, 'conditions' );
				// Если условия пусты, то пропускаем цикл
				if ( empty( $conditions ) ) {
					continue;
				}
				// Промежуточный результат AND условий
				$and_conditions = null;
				// Проходим по AND условиям
				foreach ( $conditions as $scope ) {
					$scope_conditions = $this->getPropertyValue( $scope, 'conditions' );
					// Если условия пусты, то пропускаем цикл
					if ( empty( $scope_conditions ) ) {
						continue;
					}
					// Промежуточный результат OR условий
					$or_conditions = null;
					// Проходим по OR условиям
					foreach ( $scope_conditions as $condition ) {
						$method_name = str_replace( '-', '_', $this->getPropertyValue( $condition, 'param' ) );
						$operator    = $this->getPropertyValue( $condition, 'operator' );
						$value       = $this->getPropertyValue( $condition, 'value' );
						// Получаем результат OR условий
						$or_conditions = is_null( $or_conditions ) ? $this->call_method( $method_name, $operator, $value ) : $or_conditions || $this->call_method( $method_name, $operator, $value );
					}
					// Получаем результат AND условий
					$and_conditions = is_null( $and_conditions ) ? $or_conditions : $and_conditions && $or_conditions;
				}
				// Получаем результат блока условий
				$result = $this->getPropertyValue( $filter, 'type' ) == 'showif' ? $and_conditions : ! $and_conditions;
			}
		}

		return $result;
	}

Can you check it out? Thank you!

Now we suddenly have a PHP Error on both pages with forms:
https://www.tanz-birke.de/anmeldung/
https://www.tanz-birke.de/kontakt/

The form is still working though.

The Error reads like this: Warning: Invalid argument supplied for foreach() in /homepages/30/d17491080/htdocs/tanz_birke_neu/imida-webdesign/wp/wp-content/plugins/visual-form-builder/public/class-form-display.php on line 507

We are not aware of any changes that could have caused this error.
Could you advise? Any help will be much appreciated.

I am getting this error when viewing any event. It shows up in the Author, Vendor, and Event listings wherever the description is located. eg Authors description, an error will display under the description text. As seen below.

Anyone could help me solve it as I′m not able to edit my fonts (only Basic, Italic and Oblique).

Thanks a lot in advance.

Can I check what is causing this error? The Stripe payment is on Test so you can check out with the Stripe test credit card.
