I am building a site on Drupal 7 and recently when I went into add content, not all of my content types were listed. I can manually get to the page to add the missing content types by entering the URL /node/add/missing-content-type-name. I'm thinking there must be some corruption in the database that is not aggregating all the content types on the add content page. How do I fix this?
I've tried clearing the cache multiple times. I've also update all modules and Drupal core to the latest releases.
