Hi mchag,By default admin will have all the permissions to access.Could you please check that all the bundles are in active state in system/console or try restarting the instance.Thanks,Techaspect Solutions.

Hi,We have checked this all the bundles are in active state, this is happening in our UAT environment and in our lower environments this is working fine.We are guessing this must be because of one corrupted user which was created by Authors, but we are not able to trace out which user is causing the issue.Thanks,Chagu
