Upgrading to the latest Dokuwiki ("Frusterick Manners") from a version dated 05-05-2008 then logging in as admin appeared to succeed but produced two error lines at the top of the page:
Warning: Declaration of action_plugin_importoldchangelog::register(&$controller) should be compatible with DokuWiki_Action_Plugin::register(Doku_Event_Handler $controller) in E:\XAMPP_APPS\xampp\htdocs\dokuwiki-argyle2017A\lib\plugins\importoldchangelog\action.php on line 182

Selecting the Admin breadcrumb link resulted in the following message:
Parse error: syntax error, unexpected 'new' (T_NEW) in E:\XAMPP_APPS\xampp\htdocs\dokuwiki-argyle2017A\lib\plugins\plugin\admin.php on line 128
Note: The original was on a webserver using PHP 5.6.3 whilst the new one is 7.0.23
Am I being too optimistic in making such a major change in one step? Should I install an intermediate version(s)? Any suggestions?
