Notice: Undefined property: CustomfiltersViewProducts::$showsearch in /home/domains/......ru/public_html/components/com_virtuemart/views/category/tmpl/default.php on line 54

NEXT Important -
i get this error, we can`t fix it, reset owner, chmod, not helps

vmError: Warning, the Безопасный путь is not accessible (does not exist or no permission). For safety reasons it is very important to create a folder in a path not accessible by an URL or unguessable name, create also a folder 'invoices' and 'keys' in it to store your sensitive data secure. Our suggested path is for your system '/home/domains/......ru/vmfiles/'.

to fix it i copy path from worked site, and handly write  a path and save to fix error vmfiles  path is not accessible
