Connection Refused

Hello @emilsarymsakov

I am sorry about the issue you are experiencing and I am happy to assist you with this.
I’ve checked your website and I can see that you are using Redis for DB caching.
I can also see that you are using Object Caching and caching to DISK, so I would advise disabling Object Caching in this case.
The PHP message: Connection refused suggests that there might be a problem with the Redis configuration. So you should check the Redis status sudo systemctl status redis
Also restart the Redis server sudo systemctl restart redis and try restarting your nginx server.
For the time being, also disable Database Caching to avoid piling the error.log.

Let me know if this helps!

Thanks!

@vmarko Thanks for your answer.
Just now I found out from my hosting provider that provider not use Redis, cause they use SQL. What do I need to do? Change settings in database cache, switch setting Redis to Disk? Or?

Now I switch setting Redis to Disk and errors was stopped.

Hello @emilsarymsakov

Thank you for your feedback.
So it appears that the W3TC was trying to connect with Redis and failed to do so.
Generally speaking, it’s not recommended to use DB caching and Object Caching if the only available method is Disk. The reason for this is that using disk-database caching (on shared hosting) can make your site slower. This is so because getting data from the database can be faster than getting cached data from the disk.
If however caching to disk makes your site faster, feel free to use it, and if yous tart experiencing problems, disable those settings and delete the folders /object/ and /db/ from the wp-content/cache/ folder

Thanks!

@vmarko Thank you, dear developer.

I have 2 more questions.
This errors may be related with w3tc?

And second, if i deactivate and delete w3tc will the plugin clear all its settings after itself?

Hello @emilsarymsakov

This is not related to W3 Total Cache, it seems like an invalid page entry from one of the menus or if a page (instead of the ‘blog’) is the front page.

As for your other question, hide depends on the environment, however, in most cases, all the files and folders created by W3 Total Cache should be removed, including the .htaccess rules.
The W3TC settings are saved in /wp-content/w3tc-config/master.php file
So if the situation comes that you need to completely remove and re-install W3 Total Cache, once deleted check if the following files and folders exist:
– cache folder
– w3tc-config folder
– object-cache.php (if exists)
– advanced-cache.php (if exists)
– db.php (if exists)
– upgrade folder
– delete w3-total-cache folder in wp-content/plugins/ (if exists)

I hope this helps!

Thanks!
