count() must be an array, or an object countable in (declared)

correction to the operation on lines #551-570 in the file: plugin_interface.lib.php

if ($options != null && count((array)$options) > 0) {
            foreach ($options->getProperties()
                as $propertyMainGroup
            ) {
                // check for hidden properties
                $no_options = true;
                foreach ($propertyMainGroup->getProperties() as $propertyItem) {
                    if (strcmp('PMA\libraries\properties\options\items\HiddenPropertyItem', get_class($propertyItem))) {
                        $no_options = false;
                        break;
                    }
                }

                $ret .= PMA_pluginGetOneOption(
                    $section,
                    $plugin_name,
                    $propertyMainGroup
                );
            }
        }
