W3 Total cache, AWS CloudFront and static files for redundant servers

Replies: 0

I wish to get some help after spending lots of time with all the components below, but did not get the full solution.

I am trying to build a load-balanced system that will have:
– AWS load balancer
– Two WordPress servers
– CloudFront CDN
– W3 Total cache plugin to manage the CDN integration

Per my understanding, I can configure the W3 as “Origin Pull”, create CloudFront distribution and I do not have to use a bucket, or use as “Origin Push”, create a bucket and the CloudFront will work with the bucket as its origin.

If I want to have more than one WP servers, I need a shared space for the static files. In this case I need to work as “Origin Push”? If that’s the case, I did not find any way to automatically update new content that uploaded to the web site (or updated css/JS files) rather than manually push them from the server/s to the S3 bucket. Am I missing something here?

I will be happy to better understand which configuration should I use to work with shared static files (for multiple WP servers) AND with the CloudFront.

W3 Total Cache can’t find wp-config.php

We moved wp-config.php outside of the WP root for security reasons. It is one directory up from root. Problem is that W3 Total Cache isn’t looking for it there, so even though we added the required code to wp-config.php W3 still won’t work.

I upgraded to W3TC 0.9.7.2, then I started getting this error on the console: w3tc_ga is not defined which breaks wp-admin outside of the W3TC pages.

Any chance any one has had this error before?

W3 Total Cache not working with php 7.2

Hello,

Every time I update a page, a post or do any other update in the wp admin area then new css files are generate in the cache. These new files do however start with:

<br />
<b>Deprecated</b>: The each() function is deprecated. This message will be suppressed on further calls in <b>/home/web1/gusty.se/htdocs/wp-content/plugins/w3-total-cache/lib/CSSTidy/class.csstidy.php</b> on line <b>1083</b><br />

The result is that the css files aren’t being rendered correctly and the site looks like a mess. In order to fix the css then I have to invalidate css files on CDN cache. It’s a pain not to be able to update my site without screwing up the css files. Is there some kind of solution on this problem? Would be a shame if I had to uninstall W3 Total Cache.

Intended incompatibility with WPML causes disfunction

Frederick,

I do understand, that you wish to monetize W3TC development + websites with WPML are likely to pay for W3TC Pro…

…And therefore you decided to implement fix https://wpml.org/errata/w3tc-is-not-minifying-files/ to only PRO users in Extension_Wpml_Plugin_Admin and Extension_Wpml_Plugin …

…instead of better fixing the source of problem in Util_Environment.php function home_url_regexp() or directly in Minify_Plugin.php functions remove_scripts() and remove_styles()

BUT do you know, that this way of forcing W3TC users to buy PRO versions not only sucks, but also makes their page worse? Because:
1) configured minified styles and scripts are included twice: originals + minified version.
2) Including twice some JavaScript may result in malfunctionality, like imediate closing of mobile navigation in Avada Theme.

Please, consider release of this fix to all W3TC users or at least make some effort not to include JavaScript+Styles twice, when WPML is active and https://wpml.org/errata/w3tc-is-not-minifying-files/ is not implemented otherwise.

I do not feel good about W3TC after this experience at this moment. Especially I do worry to update W3TC, because this will cause the need to reimplement changes in Util_Environment.php…

…But you made a good job with W3TC and I hope you will decide to make it work acceptable with WPML even for none-pro users… please…

The issue is occurring when HTML minify option is enabled.

As the double quotes (“) are has vanished in the version 0.9.7.2 Because of this the trailing slash is creating a problem in the attributes in which the tag closing slash “/” is not available.

For example:

<link rel=canonical href=https://example.com/bla-bla/>

In the above example how it can be distinguish the trailing slash (‘/’) used for HTML tag or it is a part of url.

I wanted to install either W3 Total Cache, WP Fastest Cache, or WP Super Cache on my site, but on the plugin page, it says none of these plugins are not available to install?

There’s a little question mark, where the install button should be and when you highlight the question mark, it gives you the following message that says;
“This plugin is not allowed on our system due to performance, security, or compatibility concerns. Please contact support with any questions”

Ok, so I’m contacting support. Why are these not available to install?

Thank you.

Hi,

We’re using W3 Total Cache on our site, and ever since turning HTTP/2 on in Apache, our sites (including subdomain network sites linked to in the footer) do not load on first attempt in Google Chrome on Mac & Windows.

A refresh will load the websites on 2nd attempt.

Other browsers look to be fine.

The 3 computers using Chrome have no extensions in common.

Help appreciated.

Web site is frequently updated with new content
The server is dedicated
Ubuntu 16.04.5 LTS
PHP 7.2.7-1
nginx version: nginx/1.13.12
Cloudflare
SSL enabled – Full

When I turn on Page cache with “Cache SSL (HTTPS) requests” (SELECTED – ON) have problem.
When I create new posts for site visitors who have already been on the site, the old content is displayed – the browser will not show the new content.

https://imgur.com/Voww2Wa

I tried to setup Purge Policy options (Front Page, Post Page and Blog Feed) but nothing happened.

When deselect Cache SSL (HTTPS) requests, all is OK.

Of course, I want to use this option, since it significantly reduces the server load. Do you know what the problem is?

Hi,
Is there anyway I can exclude certain pages from using cdn links – I am trying add structured data to the page, but the image url is being transformed to the cdn url. I want to stop this from happening as the image path should be the same as domain name. Is there a hook or function call to stop converting image urls to the cdn path if on a certain page.
Thanks

Bots not seeing files as concatenated?

February 12, 2019, 8:40 am

Replies: 1

Recently, many CSS and JS assets on our live site began appearing individually in our Google PageSpeed reports, when most of them were supposed to be concatenated and minified by W3TC (manual settings). Our PageSpeed score is halved and our GTmetrix load time has doubled.

I checked a staging version of our site in PageSpeed and GTmetrix, and it’s fine: the files show up as concatenated and minified. I tried the live site in Chrome with Lighthouse, and it’s fine also. And I cross-checked this by inspecting the html head with Chrome developer tools: it requests the appropriate concatenated and minified files. But when I analyze the live site in PageSpeed and GTmetrix, they receive all the JS and CSS as individual files, not concatenated.

We use W3TC with Cloudflare and CacheWall. Initially suspecting a problem with incorrect files cached, I tried clearing the cache in all three and turning on dev mode in Cloudflare and CacheWall to bypass the cache. No luck, and I can’t even imagine why the cache would send different files to different viewers anyway. There doesn’t seem to be a setting in W3TC to show non-concatenated files to bots (which is how I’m presuming it sees PageSpeed and GTmetrix).

I’ve even let the site sit over the weekend in case something needed to propagate or work itself out. And Googling my issue yields nothing. I’m running out of debugging ideas and concerned about PageSpeed effects on our search rankings.

Do you know why PageSpeed and GTmetrix could see the site differently than my browser, with the measures I’ve described in place?

when I activated the plugin and configured page cache and other modules everything in the backend
was fine but when I logged out and try to access it gives HTTP 500 error.
I looked for a solution on the web and I found it was an error related to htaccess rewrite.
I deleted my htaccess and I was able to access my site.
where should the code by w3tc be appended to
before #BEGIN WORDPRESS OR
after #BEGIN WORDPRESS

I also want to know what else could be the reason for HTTP 500 error?
