Undefined array key "post_install"

I’ve got a new install of 8.5 (on a server that has 7.12 on it… which may be part of the issues).

When I go to “admin” then “Studio” I get an error page with " Warning : Undefined array key “post_install” in /home/gytic/public_html/suitecrm/public/legacy/include/portability/Services/Cache/CacheManager.php on line 38"

Does anyone know how to fix this?

You may need to delete some folders from the cache folder and do QR&R.
