Hey, haven’t had the time to look yet.

The current result is wp-admin throwing There has been a critical error on this website.

What does the PHP error log show for this now that you’ve moved the file?

I have uploaded a simple PHP script to test if memcache is working and it’s fully functional (on the same page you can find a phpinfo that confirms that memcache 3.2.0 is installed and fully functional).

This is what I’ve been trying to tell you. 🙂

There are two PECL extensions for memcached backend:

• memcache – https://pecl.php.net/package/memcache – the one this plugin uses
• memcached – https://pecl.php.net/package/memcached – the one you have, but is not supported

Hope that helps.

Yeah, seems related to this https://core.trac.ww.wp.xz.cn/changeset/54448. Will take a look in the coming weeks.

For now, you can probably just add:

function wp_cache_supports( $feature ) {
    if ( $feature === 'flush_runtime' ) {
        return true;
    }
    return false;
}

Hi, what is not working? 🙂 How did you install?

Hey,

that is correct. The message means it’s not loaded into PHP (doesn’t matter if installed or not).

As for easiest way on CentOS, I think you can do it like this:

yum install php-pear
pecl install memcache

Not 100% sure, since I don’t have such a setup to test on.

Seems to timeout. If you’re using username/password (which the plugin doesn’t support yet) you can try this solution: https://ww.wp.xz.cn/support/topic/add-support-for-memcached-sasl/#post-16175580

Hi,

> Please note that memcached is supposedly better.

I could agree with newer or better maintained. The APIs for these 2 extensions are different. It would require a pretty big rewrite to make this one work with memcached instead of memcache.

> I am pretty sure the plugin is using the memcached but for some reason it wants also memcache also installed.

This is not correct. It is using the memcache extension.

Glad you made it work!

> May main problem is that our WordPress site encounters a critical error when the object-cache.php is copied to the wp-content folder.

Could you please paste me the php error log?
