Hi I am using ari image slider on
www.franziskaschenk.co.uk/index.php?option=com_content&view=article&id=154&Itemid=53 successfully. It works fine with the top four pages in this section but gives me the error :

Fatal error: Call to undefined method AriAppUtils::getLocalizedFileName() in /home6/manxmove/public_html/franziskaschenkco/modules/mod_arifancybox/includes/kernel/Module/Providers/class.ThumbnailProvider.php on line 264

wehn I select the bottom two pages. I copied the pages and the modules from previous working versions and cannot see any differences .
Can you advise please?

Hello,

Check that the latest version of "ARI Image Slider" and "ARI Fancybox" are used on your site.

See "Extensions -> Install / Uninstall -> Modules" page on Joomla! backend.
