3.5.3 possible bugs (plugin not installing, https redirects)

ee site update example.com --wpfc from --wp displays nginx helper gets installed on ssh screen, but when you login to dashboard, nginx helper plugin is missing.

Setting plugin nginx-helper, please wait...
Installing plugin w3-total-cache, please wait...

Also w3tc cache settings are mostly blank although it says some caches are set to use memcached.

Page Cache:             Disable
Database Cache:         Memcached
Object Cache:           Memcached
Browser Cache:          Disable

Another problem is when I mistakenly typed http://example.com/wp-admin while let’s encrypt is on, it didn’t redirect to https.
