Deprecated (16384) : Colon prefixed route placeholders like `:foo` are deprecated. Use braced placeholders like `{foo}` instead. /var/www/offertegiocattoli4/vendor/cakephp/cakephp/src/Routing/Route/Route.php, line: 303 You can disable all deprecation warnings by setting `Error.errorLevel` to `E_ALL & ~E_USER_DEPRECATED`. Adding `vendor/cakephp/cakephp/src/Routing/Route/Route.php` to `Error.ignoredDeprecationPaths` in your `config/app.php` config will mute deprecations from that file only.
