Move news to new webserver

If I move backup filé from old server to new one and choise to unpack it I got error that backupfile not exist. My version is 2.0.3 and suddenly stop working on my webhotel. I think it can be something with php version and they are not longer back compatible. Think they use 7.1 now. so I get this error message on my website "Fatal error: Uncaught Error: [] operator not supported for strings in /customers/1/c/8/****************/core/news.php:26 Stack trace: #0 /customers/1/c/8/****************/core/news.php(316): cn_helper_category(Array) #1 /customers/1/c/8/****************/core/core.php(2666): cn_modify_category_icon(Array, Array) #2 /customers/1/c/8/****************/core/includes/active_news.php(123): entry_make(Array, 'active', 'Default') #3 /customers/1/c/8/****************/core/includes/dispatcher.php(31): include('/customers/1/c/...') #4 /customers/1/c/8/****************/show_news.php(109): include('/customers/1/c/...') #5 /customers/1/c/8/****************/news.php(14): include('/customers/1/c/...') #6 {main} thrown in /customers/1/c/8/****************/core/news.php on line 26"       But I can log in on daschboard. thanks for all help
