Issues after upgrading to v13

I am able to get rid of error related to crisp. site application gets deployed successfully too. However I still get 404 error. It says “The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.”.

Also ever since i have fixed the crisp issue i am getting “javax.jcr.RepositoryException: javax.jcr.RepositoryException: The session pool of the pooling repository has not been initialized or closed.” CMS and console is accessible though.

Thanks
