Unable to Enable Object Cache

Hey!

Did you follow the README and configured the WP_REDIS_* constants?

If so, can you post your Diagnostics from the plugin’s settings?

@tillkruess Thank you, I have read the README file and found the constants I will have to configure. Next, I checked in few places, but could not find where I will need to configure the WP_REDIS_* constants. Can you please let me know where I have to configure the WP_REDIS_* constants?

It’s documented in the README file.

@tillkruess After reading the README file, I could only find the Configuration Options, but where to configure and how to, that I could not find. Can you please help me find where to configure and how to?

You seem skipped or ignored the section in the readme called “Installation”. Read it.

@tillkruess I read the Installation instructions in your provided link and configured the constants in wp-config.php and then went to the settings of Redis Object Cache plugin and clicked, Enable Object Cache, again the same error. Below I am providing two Google Drive links, where you will find two images, one from the WP Config file where the constants I have specified, another of the error.

Is Redis Server reachable via redis-cli?

@tillkruess I don't know how to check if Redis Server is reachable via redis-cli. After configuring the WP_REDIS_* constants in the wp-config.php, I can see the constants in the plugin settings' diagnostics. I am pasting below.

Upgrade to the latest version and post a screenshot of the Settings > Redis page.

I have updated Redis Object Cache plugin to Version 2.4.1. You will find the screenshot of the plugin’s settings page in the following Google Drive URL: https://drive.google.com/file/d/1D9W8DAwNArbJTTqYyJfItzmFZmyDuntY

Can you connect to your Redis Server using redis-cli?

@tillkruess I do not know how to do that, can you please guide me to connect to Redis Server using redis-cli?

You can Google that yourself.
