Could not analyse class: "Tx_Yag_ViewHelpers_Link_GalleryViewHelper" maybe not loaded or no autoloader? PHP Warning: Declaration of Tx_Yag_ViewHelpers_Link_GalleryViewHelper::render($galleryUid = NULL, Tx_Yag_Domain_Model_Gallery $gallery = NULL, $pageUid = NULL, $pageType = 0, $noCache = false, $noCacheHash = false, $section = '', $format = '') should be compatible with Tx_PtExtlist_ViewHelpers_Link_ActionViewHelper::render($action = NULL, array $arguments = Array, $controller = NULL, $extensionName = NULL, $pluginName = NULL, $pageUid = NULL, $pageType = 0, $noCache = false, $noCacheHash = false, $section = '', $format = '', $linkAccessRestrictedPages = false, array $additionalParams = Array, $absolute = false, $addQueryString = false, array $argumentsToBeExcludedFromQueryString = Array, $addQueryStringMethod = NULL) in /srv/www/clients/client1/web7/web/typo3conf/ext/yag/Classes/ViewHelpers/Link/GalleryViewHelper.php line 32
