CPU Spike after emptying cache
Replies: 0
My CPU and physical memory usage spiked around the time I emptied my cache. This may have happened in the past, although I don’t have a clear correlation between emptying the cache and a spike in storage usage. Aside from updating pages and subsequentially emptying the cache, those are the only tasks that took place during the spike. There wasn’t a spike in site traffic at that time.
Any ideas as to how this may or may not be related to using W3 Total Cache is appreciated.

Latest Update keeps resetting my config on loadbalancer
Replies: 0
Since the latest update I keep losing my settings for Rackspace CDN and/or I get an error about authentication even though the settings are correct. The only way to fix it is by saving the settings again.
In my case im using a load balancer on the site with settings saved in a repo. So why does it sometimes fail to authenticate? This isnt a rackspace issue because the same set up works fine on stage with 1 server.
Side question, which file is the correct settings file now? I see a master.json file but also the master.php and master-admin.php file. Why are there so many settings files and which one do i actually need to use/keep in my repo?

0.9.5.1 Caused Salesforce Captcha to Break
Replies: 1
I recently updated my W3 Total Cache to version 0.9.5.1 and realized today that I haven’t received any leads through salesforce forms since the update. It turns out that the new version of W3 makes the captcha (built-in to salesforce forms) appear blank, disallowing anyone to contact us or download content requiring forms. Is this a known issue? What is the best way to resolve it?
As of now, I have deactivated W3 Total Cache and the problem is resolved, but I would like to continue using this plugin.

Call to undefined function wp_cache_get()..??
Replies: 3
I’m updating a number of sites to WP 4.6.1. My process for each is to update all the plugins and themes, and then I update WP itself. I do this every month so I’m never very far behind.
For some reason, each site I’m updating right now is throwing this error after the files are updated:
[03-Oct-2016 23:33:14 UTC] PHP Fatal error: Call to undefined function wp_cache_get() in /home/airassoc/airassociatesmo/wp-includes/option.php on line 1113
I am not able to get the admin panel to load that point until I go in and completely disable the cache plugin. That includes the plugin folder itself as well as the individual files under /wp-content.
One of the sites I was able to get the caching plugin re-activated after completing the WP updates successfully. On another I was not able to get it to re-activate for some reason, even after disabling to apply the updates successfully.
It’s happening on every site I update with this plugin right now.

Issue with w3 Total Cache when deactivated
Replies: 1
Hello,
I spent a few hours last night trying to workout why there was an issue with Items in a Woocommerce cart not updating, fragments where actual cart page wasn’t. I’d previously turned of w3 Total Cache so I could be sure changes propagated down with some website updates.
For some reason the deactivated plugin was serving some cached content, I checked file permissions but still not sure why this was happening. Simply re-enabling fixed all of the problems, in dev (localhost) I removed the plugin manually which also fixed the problem.
Any ideas why the deactivated plugin would still be serving pages there’s not forward proxy.
Thanks

Problem during latest update
Replies: 3
Hi guys,
Just tried to update a few plugins and received the following error:
W3 Total Cache Error: some files appear to be missing or out of place. Please re-install plugin or remove /home/content/74/12109974/html/mysite/wp-content/advanced-cache.php.
Tried to reinstall via the WP dashboard, but the search just hangs and cannot seem to find the plugin.
Tried to manually install from a download but receive the following:
Installing Plugin from uploaded file: w3-total-cache.0.9.5.11.zip
Unpacking the package…
Installing the plugin…
Destination folder already exists. /home/content/74/12109974/html/mysite/wp-content/plugins/w3-total-cache/
Plugin install failed.
I’m also receiving the following on some pages:
W3 Total Cache Error: some files appear to be missing or out of place. Please re-install plugin or remove /home/content/74/12109974/html/mysite/wp-content/advanced-cache.php.

Not sure how to remove the .php file and would appreciate some guidance on how to resolve this as it has taken my site down and placed it in “Scheduled Maintenance” mode. Btw, I have removed the .maintenance file to no avail.
Thanks in advance

Since last update I am not able to add a script manually in the minify page, nor change the embed location.
Is it intentional? How can I achieve to do this? changing the embed location from the help wizard messes up the order I gave to the loading sequence.

Problem after upgrade
Replies: 2
I just updated WP3 and now on the WP3 dashboard I see the following :
FTP credentials don’t allow to write to file /var/www/vhosts/26/312513/webspace/httpdocs/wp-config.php
W3 Total Cache Error: Files and directories could not be automatically created to complete the installation.
Please execute commands manually
I have added the suggested lines
/** Enable W3 Total Cache */
define(‘WP_CACHE’, true); // Added by W3 Total Cache
to wpconfig.php manually
I have uploaded the updated wpconfig.php file and checked that these lines have been added
However the same messages keep appearing on the dashboard.
I’ve also noticed that there is a further message which states
“The plugin is currently enabled in community mode.”
I don’t know if it is relevant but the WP3 plugin was deactivated when I ran the update.

Same as the previous update, this update broke the site.
I had to rename the folder, go to the wp admin dashboard, rename the folder back to original and re-active it.

Single memcached server, many wp individual sites
Replies: 0
Hi,
I have single memcached server used by 3 separate wordpress sites using same theme and different db prefixes.
Using w3tc and memcached on all 3 for database and object caching it gets mixed up.
I tried adding “define(‘WP_CACHE_KEY_SALT’,” to wp-config but seems like w3tc ignores this setting and adds same keys to all objects “w3tc_key_” domain.com
How can I make w3tc check for WP_CACHE_KEY_SALT setting and not ignore it?
Or what’s the solution for multiple wp sites on same server with single memcached server?
Thank you.

Redis extension doesn’t save to different buckets
Replies: 2
So far, I’m very happy with the upgrade including Redis as mechanism to cache pages, objects and database queries. However, I have configured several databases to store every kind of cached object in its own redis database, i.e.: page cache in DB 1, database queries in DB 2, object cache in DB 3. But no matter if I enable persistent connections or not, it puts everything into DB 1, always.
I hope a crash is a hard thing to happend since all the keys are prefixed with the hostname and the number of the supposed DB, but anyway it is not expected, since I’d like to being able to fix a caching issue, for example, just emptying the page cache with FLUSHDB on one redis bucket, but I can’t actually do this because the plugin its putting all in the same database.
I’m storing the PHP sessions in different redis buckets, 17 and 18, so I’m pretty sure it is not the extension.
Any help would be very appreciated.
