W3 Total Cache
[resolved] W3TC Documentation? (23 posts)

    Is there any documentation on getting this setup properly with explanations of the settings? I realize that each setting has a brief description with it but a lot of them don't make sense and I don't know how to configure them. Also, I have seen the FAQs but I'm looking for more organized documentation. Am I missing something?

    the documentation is
    http://wordpress.org/extend/plugins/w3-total-cache/
    and the faq in the plugin's pages on your site.

    there are sensible defaults.

    could you be more specific on the config issue you have?

    I'd need to write a book to give more details on all of the options, I do not have the resources to do so.

    @Frederick Townes - I completely understand. I just wanted to make sure there wasn't some extensive documentation that I was missing. Thanks for creating this resource.

    @blau - Thanks for the response. As I said I'm familiar with the FAQs. I have a number of questions that are not addressed there but mainly I'm having a difficult time with the server setup.

    First of all I'm running LiteSpeed not Apache so I don't know how that affects the installation instructions. Should I be doing something differently with LiteSpeed?

    The instructions list the following steps:
    - Server Preperation
    - Memcached (Daemon) Installation
    - PECL Memcache Module Installation
    - PECL Alternative PHP Cache (APC) Installation (Recommended)
    - XCache Installation
    - eAccelerator Installation

    I've got Memecahce installed but I did not install Optcode or APC because my host told me they can cause instability with PHP on LSWS.

    In the instructions above am I supposed to be choosing one or doing them all? I guess I don't understand if they are complementary meant to work together or if they are alternatives. What makes it more confusing for me is that fact that only one says "recommended." Does that mean the others are required? If so, what's the implications of not installing one of them? Do they render the plugin useless or just impact performance?

    Another question I have is which type of page caching should I use? I have memcahe installed but under the page cache method it is under the heading "Mulitple Servers" which I assume means a CDN. I'm not using a CDN but can I still choose memcache?

    @Frederick - those of us who are not as technically skilled and experienced as you are need more detailed documentation than what's available in the FAQ to configure the plugin correctly. Most of us are new to most of the terms involved and just need simple directions to follow.

    For example, when I get this error message: "Recently an error occurred while creating the CSS / JS minify cache: Some files were unavailable, please check your settings to ensure your site is working as intended."

    I don't know how to fix it. I've added all the files the help wizard suggested, then deleted 4 of them because I got an error saying they had invalid file extensions.

    However, I'm still getting the same error message about some files being unavailable. Which files? How do I make them available?

    I know you're going to say "fill out a bug request" - but I'm not sure it's a bug - it's just I have a need for more specific direction with this error.

    The plugin rocks and I will continue to recommend it to friends and clients - just need to get this minify part (in conjunction with using the CDN feature) dialed in so I can feel totally confident.

    Many thanks,
    Web Weaver

    @CatScholz74 - you have a lot of CSS within your main HTML template. Considered integrating it into the main stylesheet?

    @mattloak - litespeed doesnt affect the W3TC set up, it's just a better handler than apache. however it's not recommended with APC usage (contrary to what I see on a few sites). I honestly found Litespeed a waste of money because there are alternative setups with free and very efficient software alternatives to apache and so on.

    @braddor - thanks for taking a look at my site - my BuddyPress/BuddyDress theme has so many stylesheets! would I use the CSS Minify feature of W3 Total Cache to achieve this or a plugin such as CSS Sprites? many thanks!

    @CatScholz74, CSS Sprites solves a different problem. First minify the CSS files. Then you can use spriteme.org to make corrects to your CSS files.

    @Frederick - thanks - whenever I enable the CSS Minify and add the files suggested by the wizard, then delete the invalid files, the site looks like this:

    http://www.catswebweave.com/wp-content/uploads/2010/08/Picture-24.png

    So I have diabled CSS Minify until I know what I am doing wrong in the configuration.

    Any assistance with this is greatly appreciated!

    Sorry, missed some previous questions:

    First of all I'm running LiteSpeed not Apache so I don't know how that affects the installation instructions. Should I be doing something differently with LiteSpeed?

    It doesn't. You can only use one opcode cache at-a-time and you need to know how to configure litespeed so that it will actually work. Ask your hosting provider to avoid instability.

    Unless you have multiple servers you don't need memcached. The drop down menus for the methods on the general settings tab tell you which method to use for which cases.

    Things that are recommended are just recommended. You don't have to install any software for W3TC if you don't want.

    For example, when I get this error message: "Recently an error occurred while creating the CSS / JS minify cache: Some files were unavailable, please check your settings to ensure your site is working as intended."

    When the minify cache was built, a file wasn't available to be minified so it was skipped. So you have to check to make sure that the resource is in fact available or the error could be indicative to resource scarcity issues on your server.

    whenever I enable the CSS Minify and add the files suggested by the wizard, then delete the invalid files, the site looks like this:

    http://www.catswebweave.com/wp-content/uploads/2010/08/Picture-24.png

    Enable preview mode and then delete your minify settings, save the settings, then use the help wizard again, apply and close after making your selections, then save settings again and click preview. Edit settings until things are ok, then deploy settings.

    Thanks for the direction, @Frederick - after following your suggested procedure, I tried deleting the main stylesheet: wp-content/themes/bp-fun-child/style.css from the minify settings in order to get the site to display properly.

    This was a total guess on my part, but it worked. I still get the error message about files being missing, however.

    My next challenge - to reintegrate the Featured Content Gallery in the header. Will keep you posted.

    Again, thanks.

    I'll take a look into what may be causing false positives.

    Hi again, @Frederick - Any idea why the option to host minified JS and CSS files with the CDN is greyed out here?

    http://www.catswebweave.com/wp-content/uploads/2010/08/Picture-1.png

    Also, I can't seem to figure out why the JQuery library is not being loaded on my wp-e-commerce shopping cart page here and I get a constant spinning wheel as you can see here:

    http://www.catswebweave.com/wp-content/uploads/2010/08/SpinningWheelWpECommerce.mov

    Using preview mode, I found that it seems to be a problem with the CDN and not the Minify feature. I've made sure all the files are there in the WP-e-commerce folder on the CDN and the permissions are correct.

    Any ideas?

    Also, here are my CDN settings:

    Are you sure that minify is enabled on the general settings tab and CSS and JS is enabled on the minify settings tab?

    Ah @Frederick, thanks - in preview mode, they both enabled, but live on the site, CSS Minify was enabled and JS Minify was NOT enabled.

    So I renabled JS Minify, cleared the cache, and the setting for hosting the JS/CSS Minify files with CDN is still greyed out. Here is the screenshot:

    http://www.catswebweave.com/wp-content/uploads/2010/08/Picture-11.png

    And I'm still getting the vague error message about the missing files.

    Thanks,
    -WebWeaver

    This option is only available when rewrite minify URLs is enabled.

    I came across this excellent guide yesterday. It might help explain a lot to those new to W3 Total Cache.
    http://zemalf.com/1443/w3-total-cache/ - I recommend checking out the e-book zemalf has on scribd. The link is on this page.

    Additionally this post helped to explain opcode caching and setup APC. http://www.virtualmin.com/node/15258#comment-69432

    @Frederick, are you sure this isn't a bug in W3TC? I have a WP site that I just moved from an server running apache to a server running litespeed and I ran into the exact same problem. I was my main style.css that was causing the issue. The wierd thing is that I have 2 other wordpress installations that I moved to another litespeed server that had the exact same problem, and all were running W3TC with different themes.

    Do you know what could be causing this?

    my blog is thepowerofbeing.net and I am trying to activate my scribd plugin after updating to 3.2.1 and I get the following error message:
    Fatal error: Cannot redeclare ipaper_head() (previously declared in /home/dmolini/public_html/wp-content/plugins/wp-ipaper/scibdipaper.php:103) in /home/dmolini/public_html/wp-content/plugins/simpler-ipaper/scribd-ipaper.php on line 71
    Please tell me what to do

    @dmonlini, I'm not convinced that error is related to W3TC.
