hi how to uninstall the plugin completely?
it seems high volume of database have been generated, and when I try to delete the plugin it makes the site down with white page…. so I could only deactivate it
]]>I found that my WordPress site is not loading, but when I remove the file object-cache.php, it will work again. why is it happening?
and do I need to clear cache? anyway to do so?
Thanks
]]>I have a site with 500,000 registered users.
I set
Apc.shm_size=4G
I saw a lot of caches of user information written to the database in mysql slowlog.
I don’t feel very good. Can I turn off the L2 cache?

One website shows the wrong homepage, and in the admin pages, it disables plugins from one another, because the folders are not present. The plugin merges both websites into “one cache”.
Is there a way to prevent this?
]]>I’m seeing a strange problem that when I have the object-cache.php file in my wp-content directory then my pagination queries are repeating the same posts over and over.
I have an out-of-the-box WooCommerce installation, and I’m using a theme which requests pagination over ajax. The products seen on page 1 sometimes are often (but not always!) shown on page 2, 3, 4, etc.
]]>After installation and activation I keep getting the “Warning! Missing LCache database table, which is required by WP LCache object cache.” error message.
I followed the installation instructions exactly, tried deactivating and reactivating the plugin (which should trigger creation of the tables), also removing and reinstalling the plugin, but the error message stays.
It seems the Lcache database tables are not being created upon activation of the plugin. I checked the tables via phpMyAdmin and I could not find a table wp(prefix)_lcache_events.
My WordPress site (4.8.2) runs on a shared webhosting server (Apache), PHP 7.1.9 with APCu extension 5.1.8, and MariaDB 10.1.24.
Do you have any ideas or suggestions that will help me to get LCache working?
]]>Hi, as soon as I create the stub file, the site goes from loading pages in less than a second to 1-2 seconds. The site goes fast again once I delete the file. No errors in Javascript console or nginx error file. How do I troubleshoot this? Using Ubuntu 16, PHP7, MySQL (Percona), NGINX, Multisite WP. I noticed that one of the CPUs spikes momentarily per page, as opposed to not having the stub installed. Thanks
]]>I like the concept of this cache, and decided to try it on our production servers last night during somewhat modest traffic.
APCu was caching correctly, at least according to the APCu status page showing hits/misses and memory usage. We were getting about 3500 requests/sec on the APCu cache on each of our two web servers.
CPU usage on our two web servers did go up by about 25-30%, which I suppose makes sense given how this works.
However, the load on our MySQL database skyrocketed and we ran in to unusable limitations with maxed out IOPS, high database CPU usage and ultimately maxing out our PHP-FPM pool when it spawned more and more processes.
I guess I can provision more IOPS on our DB server and try again, but any guidance here? The improved performance over memcached or redis might come at the expense of having to trick out the database server to support this style of caching.
]]>Hi,
Could I use WP-LCache with other WordPress cache plugins, like “w3c total cache”, “wp-rocket”? Because of features likes html minification, css minification,defer js loading……etc. Or Just one plugins work in same time?
]]>Hello, is there anyway to flush the cache apart from restarting the PHP
does this plugin work with your plugin?
Hello
why this plugin states Lache instead of Apcu cache?
I know from the support guide it needs Apcu, However, is quiet confusing

Create a Form, Goto Settings, and click on Reports:

I uninstall WP LCache, remove object-cache and everything works fine. This is the first error I’ve seen with WP LCache installed. Hope it’s something that can be reproduced on your end. I even deleted All forms thinking it was form related. Still same error.
Please let me know what else to try.
Thanks
