Now, my start page says:
Fatal error: Declaration of syntax_plugin_wpre::handle($match, $state, $pos, &$handler) must be compatible with dokuwiki\Extension\SyntaxPlugin::handle($match, $state, $pos, Doku_Handler $handler) in /var/www/html/lib/plugins/wpre/syntax.php on line 74
dokuwiki\Exception\FatalException: Declaration of syntax_plugin_wpre::handle($match, $state, $pos, &$handler) must be compatible with dokuwiki\Extension\SyntaxPlugin::handle($match, $state, $pos, Doku_Handler $handler)
An unforeseen error has occured. This is most likely a bug somewhere. It might be a problem in the wpre plugin.
More info has been written to the DokuWiki error log.
And that's ALL it says - no way to get to any of my pages, etc. How do I recover my wiki?
