[Plugin: W3 Total Cache] How to Uninstall with no Admin Panel

  • Hi, I am trying to figure out how to get my WP administration panel back. When visiting the site http://mysitename.com/wp-admin the screen is blank. I have tried un-activating all the plugins through phpmyadmin, but the white screen persist. I have reason to believe it may be the W3 Total Cache plugin.

    How can I uninstall this plugin manually? I have tried deleting all the files in the plug-in folder as well.

    The WWW version of my site works fine. The non WWW version shows a blank screen. Trying to access the administration panel from either route retrieves a blank screen.

    Any ideas would be very welcomed as we can’t edit the site like this. (

    Thanks!

  • I’m sorry (and surprised) to hear that this happened. There must be some conflict with another plugin you are running.

    In any case, make sure to also remove: advanced-cache.php, db.php, w3tc/, w3-total-cache-config.php from wp-content/ in addition to wp-content/plugins/w3-total-cache/.

    And if you have a staging server with the exact same configuration I would be curious to find out what the conflict is.

    i am trying to remove w3 total cache from my site and it says i don’t have permission to do so… wtf? Frederick could you possibly please enlighten on how to remove… thanks…

    heres the error:

    550 Could not delete db.php: Permission denied

    and i changed the file permissions all over the place… any hellp much appreciated

    Is there a really a need to curse? Those permission issues have nothing to do with W3TC.

    W3TC creates files owned by the same user + group as your web server (standard operating procedure), so if your FTP or SSH user doesn’t have access to remove them and you cannot change the ownership/permissions yourself, contact your web host for assistance.

    My site wasn’t updating on the frontend. My RSS feeds weren’t working right. Low and behold, it was this very issue. I followed your removal tip and it fixed the site. Excellent, thank you!

    It would be useful to find out why the remaining 7% of users are users having issues. If anyone has constructive feedback it’s well appreciated.

    Frederick,

    I had similar issues when I installed w3tc. I ended up with the horribly frightening white screen of death where my admin panel should have been. I used Jared Hienrich’s post: How to troubleshoot WordPress “White Screen” of Death to recover. I also had to reload several times and remove files as prompted by missing file messages that came on the browser window.

    I still have some of the w3tc files installed, but my site finally came back. I have not yet tried to reinstall the plugin, but I very much want to. I will remove all plugins to an temporary folder and leave “plugins” empty and try again.

    Then I will reinstall each plugin, one by one until I find out which of them is the evil culprit.

    Will let you know.

    Ok, but evil is a strong word. There are 9000+ plugins and no one can promise compatibility with them all for the same reason.

    i too had the same problem this is the worst plugin i have ever seen and this guy fredericktownes is just full of attitude and always shows this figure, he just praise himself and his plugin.
    my blog is totally fucked up after using this plugin.
    he is not willing to help without money.

    this plugin wasted my years hard work.
    now i am not gonna leave this person.
    i am finding all options and talking to my lawyer and i am gonna show him a real bad time now.

    @rounak: In my own experience, Frederick has been very helpful all through even without me paying him a dime. You’re talking about calling your lawyer and stuff but you seem to forget the fact that every FREE PLUG-IN comes with its perks and some just don’t work.

    I’ve a had a plug-in mess up my site but I was fortunate enough to have a backup of my database which saved the day.

    I hope you can recover your blog soonest and please cultivate the habit of backing up your database EVERYDAY as shit can happen @ any time.

    Cheers

    @rounak contacted me for a “request for quote” via my web site; a quote was provided. Had he submitted a bug submission he would have received support as @strictlyonlinebiz testified above.

    I actually liked this plugin until I upgraded to WordPress 3.0.

    I’ve been having some issues with slow loading. Dreamhost told me that there are known compatibility issues with W3 Total Cache and WordPress 3.0. Since this is the “real bad time thread” I thought I would join in. I’m not sure if my problems are related to Dreamhost which I suspect or W3 Total Cache which worked fine for me prior to Wp 3.0.

    I’m not sure if users realize that WP 3.0 was a significant change in how WordPress works under the hood. Anyway, v0.8.5.2 of W3TC was never flagged as compatible with WP 3.0, still many users upgraded anyway. If you wish to continue using W3TC, v0.9 (the development version) is quite stable, compatible with WP 3.0 and available here: http://wordpress.org/extend/plugins/w3-total-cache/download/

    I was facing with same issue during update to 0.9 (seems is beta) and receive blank screen of death.

    A good practice to locate problems try to setup WP_DEBUG into wp-config.php
    define('WP_DEBUG', true );

    Problem was located into /var/www/xxx/wp-content/plugins/w3-total-cache/lib/W3/Plugin/TotalCache.php when try to using DOMDocument

    at line:
    $dom = new DOMDocument();

    That seems was missing on my production server and from here was the fun begin.

    I suggest as required modules to be checked when plugin is installed and be sure all requirements are accomplish.

    Happy caching!

    Thanks I realize that. Actually, the issue is the module there behaves differently in different minor versions of PHP, so I changed the implementation completely.

    Frederick, Firstly, I love this plugin – it is by far superior to WP-SC. I have one issue though, which I hope you can resolve for me. I recently deactivated W3TC after it wasn’t compatible with WP3.0. During this time, I switched server. Now that W3TC is back and compatible, I tried to run it again, but when I go to activate it through the Plugin screen, it’s saying it cannod CHMOD to /home/path/etc – but this path is from my OLD server and the current server path is very different! I have deleted W3TC many times, but still problem persists. Is the path called from the database?
