Unable to verify your data submission.

Hi

After the recent update of Yii2 using composer i have been getting the following error. Please guide me how to resolve the same -

exception 'yii\web\BadRequestHttpException' with message 'Unable to verify your data submission.' in /home/maverick/Lampstack/apache2/htdocs/lems/vendor/yiisoft/yii2/web/Controller.php:109

Please update your main layout file by adding this line in the section: . This change is needed because yii\web\View no longer automatically generates CSRF meta tags due to issue #3358.

I setup basic and avanced projects from composer today and ran into mysql connection errors due to /Application/MAMP/tmp/mysql.sock not pointing to /tmp/mysql.sock where I have MySQL5.4.4. Once I fixed these and restarted Apache, opened both frontend and backend side by side with basic in chrome browser. However , during first signup i saw same error - "Unable to verify your data submission". I checked that my latest View already had the Html::csrfMetaTags() lines. A full refresh of page fixed it however. There after been running randomly into above error upon logging in with admin/admin in basic and new user created in frontend/backend. Also getting this error on login at times - "Method Not Allowed. This url can only handle the following request methods: POST. Method Not Allowed (#405)
