Hello.
There is a use of undefined property in the code of batcache.php:
PHP Warning:?Undefined property: WP_Object_Cache::$no_remote_groups in /mnt/efs/wp-content/plugins/batcache/batcache.php on line 57
Probably this is due to some recent API changes in WP.
Thank you.
]]>There is a mistype in the Installation instruction. You have it like this:
…Install the “PECL memcached extension” and…
The issue with “PECL memcached extension” link. It says “memcached” while should say “memcache”; the URL is correct. This is not a minor mistype because we have actually two different extensions — “memcache” and “memcached”.
]]>Ok i so i turn on WP-CACHE on the WP-Config
but i don’t see the file advanced-cache.php
in the drop-in plugins…
now i go to my server files and check the plugin folder.
i see we have there advanced-cache.php
my question is if to move the file and remove it from your plugin folder after i move it to /wp-contact
or to duplicate him and create 2 files on in your plugin folder and one in the wp-contact folder…
the same thing with the other file in the folder: batcache.php
in the instruction you said to take him out from the folder and put him
like that in the folder himself of the plugins without folder. so i need to delete the bat cache folder and move the files? or duplicate them?
what to do? the first or the second?
]]>Hello,
does it support and how can I insert in wp-config.php the unixsocket link where Memcached is installed and working?
Thank you!

Is there the chance to avoid using Memcached on a specific post with, maybe, a filter?
]]>would be nice if you integrate “auto-copier” like in memcached plugin’s index.php
]]>My webhost company has activated the memcached service for my account and they gave me a door to use it, but after that I enabled batcache, not only I can’t find a place to insert the number of the door of my account, but I totally can’t find a link/page to administer the batcache manager. please help!
]]>I’m not sure if the developers of this plugin still follow the GitHub activity on this plugin?
We require PHP7 compatibility and are using this plugin.
As the latest code is not PHP7 compatible, I have fixed the PHP 7 compatibility issues. The pull request can be found at https://github.com/Automattic/batcache/pull/72.
Only 2 lines of code are changed so I hope this will be adopted asap.
]]>Hi
I’d like to use batcache with memcached. I have everything installed but how do I set the IP of my Memcached server(s)?
]]>Hi there,
Batcache’s description mentions that it requires memcached, however I’ve talked to a few folks who seem to think it’d run on any object cache, including Redis. Is that so?
]]>I’ve installed and enabled according to your guidance, but still: it does not do anything. Memcache is enabled, ive checked, but also SG CachePress refuses to activate.. So i assume a problem with my Memcache, but i dont see where:

]]>I see there are some big name authors on the plugin but with a last updated date of 2012-12-11 and a number of errors upon activation, I’m wondering if it is worth using.
The errors I see upon activation:
Notice: Undefined variable: batcache in /srv/www/sentient.ai/public/wp-content/plugins/batcache/batcache.php on line 11
And:
The plugin generated 155 characters of unexpected output during activation. If you notice “headers already sent” messages, problems with syndication feeds or other issues, try deactivating or removing this plugin.
I remember being at a Meetup in which they mentioned WordPress.com was actually using Batcache or some derivative of it. I also remember some reasoning as to why the plugin is never updated, but I can’t remember what that is.
I like the fact the solution gets around writing files to system. That’s primarily why I’m looking at it as a solution currently.
]]>Observed this error today…
Notice: Undefined variable: batcache in wp-content/plugins/batcache.php on line 12
To fix it I added the global $batcache; line before the first use. If you want a full patch I can generate one…

Hi.
Is there a way to stop caching for specific plugin ?
Regards.
Hi we have two webheads under one Varnishd load balancer. The memcache server sits on the same VPS as the load balancer.
We are trying to use batache to manage memcache on the site. However, everytime we switch batcache in we see the following problem.
A new user comes to the site.
Registers.
Activates their account.
CANT LOG IN.
At this point the user has been created, but only deactivating batcache will cause the cache to clear and allow the user to log in.
We have experimented with other memecache plugins (wp-ffpc) and didnt have this issue.
Is there some way to exclude either the homepage or wp-login.php from ever being cached?
Thanks
]]>Hi,
can i use this plugin beside of wp-super cache?
is this plugin required memcached to work?
i’m newbie!
]]>I run WP on Ubuntu 12.04 x32 + Nginx and just notice if I run batcache, it return with HTTP/1.1 502 Bad Gateway.
Is there any configuration that I need to tweak?
]]>How do you suggest doing this in wp-config…
in advanced-cache.php
// This is the base configuration. You can edit these variables or move them into your wp-config.php file.
Adding an example under FAQ would be useful. Thanks in advance.
]]>Can the authors of this plugin please review and update the compatibility of the plugin to 3.6.1? I have done some of my own tests and it seems everything is working just fine.
]]>Hey All
Batchache has saved me the past week so thank you for the code!
My question: How can I exclude all files in a specified directory from the cache?
Thanks
]]>I just installing this plugin but when I have finished I see the new plugin called Batcache Manager, but I can’t see batcache plugin.

I come back an hour or two later and see the following comments meaning the cached file from hours ago is gone and a new one was just generated 116 seconds ago.
Why isn’t the first cached file still around?

]]>I’m using APC Object Cache Backend together with batcache and both seem to be working. Batcache writes debug info inside the head tag and page load is markedly faster once it’s cached the page.

ENDIf I use Memcached Object Cache instead of APC Object Cache Backend memcached stats will have some updated information. I’d expect it to work the same with batcache but it doesn’t. Any ideas why that could be?
edit: I shut down memcached and batcache still seems to be working. For example new debug info is still added to the head tag. Is that possible? Could it be using APC Object Cache Backend? I’m confused.
Using Safari, Opera and Chrome in OS X statistics are added within the head tag and pages load faster, but not using Firefox 21.0. No add-ons are active.
I’m using APC Object Cache.
]]>Hi, how do I tell Batcache not to cache pages from mobile user agents?
The example in advanced-cache.php says
$batcache->unique['mobile'] = is_mobile_user_agent();
Where should I put the function is_mobile_user_agent() and define the user agents?
Plus, do I need to still need to declare var $unique = array(); if I have is_mobile_user_agent()?
Thank you for your time.
]]>You should remove this from the description, It’s a nice thing to say but tests results seem to show Batcache is either just as fast or faster.
]]>It’s not as fast as Donncha’s WP-Super-Cache
I’m currently using BatCache successfully (it’s awesome by the way!!) on my website – just wondering if there’s any way of having the BatCache comment stats displayed in my template’s footer, in place of the standard WordPress “x queries in y seconds” text?
Help appreciated!
]]>We found a peculiar issue where if a request’s If-Modified-Since date does not match the cached response’s Last-Modified date, it results in a negative Cache-Control max-age, which we found is interpreted by Akamai to cache the response forever (at least in the configuration we’re using).
To reproduce, hit a URL (e.g. a feed) a couple times to ensure Batcache saves the response in the cache:
$ curl -Gis 'https://local.example.com/tag/lorem/feed/'
$ curl -Gis 'https://local.example.com/tag/lorem/feed/'Example headers returned:
HTTP/1.1 200 OK
Date: Thu, 24 Jan 2013 00:30:46 GMT
Vary: Cookie,Accept-Encoding
Last-Modified: Wed, 09 Jan 2013 19:38:59 GMT
Cache-Control: max-age=300, must-revalidate
ETag: "726c4bddc70a4ccc0d6c0b77abb97e20"
Content-Length: 3380
Content-Type: text/xml; charset=UTF-8Note the Last-Modified: Wed, 09 Jan 2013 19:38:59 GMT. If you do a request with this time as the If-Modified-Since:
$ curl -Gis -H "If-Modified-Since: Wed, 09 Jan 2013 19:38:59 GMT" 'https://local.example.com/tag/lorem/feed/'You get the 304 response as expected:
HTTP/1.1 304 Not Modified
Date: Thu, 24 Jan 2013 00:32:53 GMT
Vary: CookieBut if you try supplying a different date as the If-Modified-Since date:
$ curl -Gis -H "If-Modified-Since: Wed, 09 Jan 2013 19:00:00 GMT" 'https://local.example.com/tag/lorem/feed/'
HTTP/1.1 200 OK
Date: Thu, 24 Jan 2013 00:35:12 GMT
Vary: Cookie,Accept-Encoding
Last-Modified: Wed, 09 Jan 2013 19:38:59 GMT
Cache-Control: max-age=-1227073, must-revalidate
ETag: "726c4bddc70a4ccc0d6c0b77abb97e20"
Content-Length: 3380
Content-Type: text/xml; charset=UTF-8Now you get a negative value for the max-age.
The patch is simply to prevent negative values: https://gist.github.com/4616240
