Using Google Chrome, I can get into the back end, but can’t navigate to Plugins, Pages, Dashboard > Home,
From another instance in Opera browser, from within Total Cache, when I click to Plugins, I sometimes receive the “500: Internal Error, This website is unavailable at the moment.”
The error types are inconsistent. When I click "Posts," I get a "500 error. When I click "Pages > All Pages," same error. Now when I click "Plugins," I get 500 error.
On this site, this a.m. I tried to install the “Hummingbird” plugin from WPMUDEV.com.
