Trying to access array offset on value of type null

Hi @strarsis,

Sorry to hear you’re having trouble. Is this on a Pantheon-hosted site or elsewhere? Is WP Redis working for frontend requests?

@danielbachhuber: Hi Daniel, thanks for your response.
This is _not_ on a Pantheon-hosted site. nginx, PHP-FPM and a local Redis server are used.

This is the configuration (development with local Redis server):

// Redis cache server (WP Redis plugin)
$_SERVER['CACHE_HOST']        = 'redis';
$_SERVER['CACHE_PORT']        = 6379;
$_SERVER['CACHE_PASSWORD']    = '';
$_SERVER['WP_CACHE_KEY_SALT'] = 'test-site';
$_SERVER['CACHE_DB']          = 0;

Thanks @strarsis!

Looking at this a little further, it appears the wp_redis_get_info() function doesn’t respect the value in $_SERVER, even though other parts of WP Redis do.

Can you see if this pull request fixes the problem for you? If so, I’ll merge it and tag a 1.1.2 release.

@danielbachhuber: Thanks! Yes, with the PR applied it works.

What still baffles me is that why it works on some other sites but not on this one.
I am using the same configuration for these sites. Maybe an updated of this plugin in the meantime introduced this issue?

Great! I’ve tagged a v1.1.2 release with the fix.

Re: other sites, I’m not sure. Maybe they have some code somewhere setting $redis_server from $_SERVER? Not much has changed with WP Redis in the last couple of years…
