Problem enabling Default Object Cache

I added define('ENABLE_CACHE', TRUE); to my wp-config.php file and I created a cache directory under wp-content with permissions 755. No files are appearing in that directory and the “server status” plug-in says:

Page Cache (Plugin): Disabled
Object Cache: Disabled

Background:
I have a long-running blog with WordPress 4.7. In the past it has has a number of cache plug-ins, including WP Cache, WP Super Cache, W3 Total Cache and most recently the Falcon caching engine in WordFence. Presumably all of those prior cache solutions have been removed according to the instructions that come with them.

Things I tried:

– Re-installing WordPress 4.7
– Deleting an advanced-cache.php file I found in the wp-content directory
– Deleting the wp-content/cache directory to see if WordPress would re-create it (it didn’t).

Server status report:
