W3 Total Cache – Admin Login 404 Screen of Death

  • I guess that this is an offer to Frederik Townes – it seems as if W3 Total Cache has corrupted some aspect of my nascent web effort. But as it is still in development and has not content I wondered if you wanted to log in and check what actually caused the problem before I follow instructions and delete all of the elements of the problematic plugin.

    Essentially after loading the plugin – everything worked – but after logging out and back in, I got the dreaded Error 404 when trying to access the admin panel.

    I posted a support query on the Troubleshooting Forum last night, but for some reason it was closed? I simultaneously logged an issue with GoDaddy who replied:

    ================
    Upon reviewing your account, I was able to successfully connect to kim4pilates.com/wordpress. However, the URL ‘https://kim4pilates.com/wordpress/wp-admin’ currently resolves to 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/57/7600657/html/wordpress/wp-content/advanced-cache.php.”

    You may need to review any plug-ins you currently have installed, or uninstall/re-install the application. You may also want to do a search on your favorite search engine or consult with a community forum online as other users may have encountered similar problems in the past and may offer helpful solutions.

    NOTE: We cannot provide application support after installation. For post-installation support, please contact the application vendor through their web site and/or use your favorite search engine to research the issue.
    ================

    I had earlier tried to clear my browser cache, delete my .htaccess and renamed my plugins folder – none of which worked. So before I delete everything – as I am too new to understand too much at this stage, and as I cannot log in I cannot log a bug report, I wondered if you wanted to do your own troubleshooting?

    Please reply and we can work out how to go forward.

    Thanks
    Ian

  • I’m not understanding the story here, you activated W3TC on a clean WP installation and the entire thing broke?

    I don’t know “exactly” what broke (above post) but that file remains in directory after W3Cache-plugin is removed. Also W3Cache changes stay in wp-config:

    (top)
    /** Enable W3 Total Cache **/
    define(‘WP_CACHE’, false); // Added by W3 Total Cache

    (bottom)
    /** Enable the WordPress Object Cache. */
    define(ENABLE_CACHE, true);

    While these files and settings are still present it can do some funny things to paths: login (404), empty spam (404) etc.

    I had to spend a lot of time trying to figure this out.

    If plugins are doing things you aren’t aware of, familiar with, in control of etc. I would suggest not using them. If you want to cache files you can use this outline for .htaccess. I included a deflate (compress) option here also.

    # compress text, html, javascript, css, xml:
    AddOutputFilterByType DEFLATE text/plain
    AddOutputFilterByType DEFLATE text/html
    AddOutputFilterByType DEFLATE text/xml
    AddOutputFilterByType DEFLATE text/css
    AddOutputFilterByType DEFLATE application/xml
    AddOutputFilterByType DEFLATE application/xhtml+xml
    AddOutputFilterByType DEFLATE application/rss+xml
    AddOutputFilterByType DEFLATE application/javascript
    AddOutputFilterByType DEFLATE application/x-javascript

    </FilesMatch>

    # NONE
    <FilesMatch “\.(pl|html|htm|php|cgi|spl)$”>
    Header set Cache-Control “max-age=20, must-revalidate”
    </FilesMatch>

    ##Deny access to all CGI, Perl, Python and text files
    <FilesMatch “\.(cgi|pl|py|txt|cfg|settings)”>
    Deny from all
    </FilesMatch>

    This will give you total control of your site/blog and if you want to remove it – it’s gone – no side effects.

    This is the way I set up my own site. You of course can change anything you like, play around with it. Always use something like rexswain’s http tool to make sure thing are working and you’re getting nice 200 codes.

    If you guys temporarily deactivate other plugins while W3TC is running does the issue keep happening? Also are there any errors in your web server error logs?
