[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 https://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!

  • One other thing that I’ve been noticing, wp-content/w3tc/ has permissions that exceed any that I have via FTP or CPanel.

    I don’t know what this means.

    This means that I’m unable to delete the folder on the server. I have to contact my hosting provider to remove the folder.

    W3TC simply has the same ownership and group as apache on your web server. It is the fault of your web host if your user/group doesn’t have permissions to modify files created by the web server. If I were you I would complain to them about that oversight on their part.

    But if the W3TC plugin creates the folder, how do I not have permissions to edit it?

    I agree somethings not right, as that’s the only folder/file that W3TC creates that I can’t modify due to permissions.

    Not sure how or why it’d have different permissions than everything else.

    I don’t know, that is a question for your host.

    Hi
    Installing w3TC crashed my site. WWW is blank page and so is wp-admin. I did remove W3TC from the plug-ins folder via ftp. Everythings still blank. Could you PLEASE help? Thanks in advance.

    Did you remove all the files noted on page one of this post? You need to get rid of more than just the plugin.

    Figured it out @pprod?

    Thanks guys. I eventually got this plugin running on a WP 2.8 site that gets up to 30k per day and WOW very big difference in performance. Runs awesome!

    @bloggerdesign – I had that same /w3tc issue (would not delete directory) when trying to uninstall this on a WP 3.0 site on KnownHost VPS. But they simply deleted it for me. I ended giving up trying to install this plugin on that host and stuck with WP Super Cache for now. Still not sure what went wrong there.

    @fredericktownes – I really appreciate how active you have been out here supporting your plugin and trying to answer all of our questions. I know it must get annoying at times…a sincere thanks amigo!

    Anyhow, I was checking back to see if people are still having issues running in WP 3.0 because I really want to update the 2.8 site above and still have some concerns about compatibility. At the moment all plugins (including W3TC 0.9.1.1) and the theme (thesis) work great, and this live 2.8 site is hosted on LiquidWeb dedicated server.

    I’m also starting to believe that the issues many people are having may be hosting related in some way, so I wanted to list these 2 hosting experiences (bad and good) to compare notes and try to narrow this down a bit more.

    Anyone here have a problem running W3TC and 3.0 with LiquidWeb? Or care to mention the host they are having problems running this on?

    I’ve been in contact with numerous liquid web and WP 3.0 users. They’re doing fine.

    Update: I upgraded that LiquidWeb site mentioned above to WP 3.0 with W3TC 0.9.1.1 and it’s working great. Thanks again.

    I noticed you have a new version out that fixes a bunch of bugs. Will try that on my KnownHost site and see what happens this time.

    Requires WordPress Version: 2.8 or higher
    Compatible up to: 3.1
    Last Updated: 2010-9-6

    Compatible with 3.1? or 3.0.1?

    I’m still working on a couple of test sites on a couple of different hosts to try and get this working…

    • template fallback/failover issues in IE with woothemes/delegate on a Virtualmin CentOS site using APC OpCode
    • /wp-admin 404 issues on a Cpanel CentOS site using disk caching

    First for @bloggerdesign – We had an hsphere server that was doing that last year. Anytime we used auto install or auto updates, the server was assigning the wrong owner to the directories and files. Server techs were able to delete any that really stuck hard. Some I was able to rename or manually upload over-top to get the permissions corrected and then could work with them again. Server techs felt there was a mis-configuration or corrupted file for one reason or another. They did some fresh re-installation of some of the core files on the server and the problem stopped. I just wanted to let you know what happened in our situation because I think it’s unlikely that the plugin actually was the cause and it might help if the problem happens again for you.

    Frederick,
    I had that same white admin screen issue, which is no doubt a plugin conflict. When I have more time, I’ll try to pinpoint which one it is. The frontend of the site was not affected, so if I figure out which plugin conflicted, maybe it’s an enqueue script that I could find a work-around for. My question though: after removing the plugin and getting the admin back (which I did with no problems) I do see the additions to the htaccess. But it actually improved the page speed score. The site is working fine. Will the additions to the htaccess still help without the plugin active? If you don’t think it should be, I’d prefer to remove the lines so they’re not causing confusion later on, but if they can still help that would be great.

    Thanks much,
    Dzynit

    Just to give Frederick Townes some credit, this plugin is amazing. Sure it is a bit overwhelming to set up at the start. If you are still playing around with your site, chanign plugins, designs, widget then you don’t have to enable everything at once.

    Even if you only enable browser and page caching the site will be faster than than what supercache provides – for my site at least.
    But if you add object, database caching and minify the difference will be huge.

    There are some real nice installation tutorials. This is the one I followed: https://www.strictlyonlinebiz.com/blog/w3-total-cache-speeds-up-wordpress/1570/
    It worked fine and now, after optimization, the site runs way way faster.

    Once you got it running it is an amazing plugin, even though google downlaoded more pages a day, it used only a fraction of transferred megabytes and the time spend downlaoding a page went from 5.6 seconds to 380ms …

    Nevertheless:
    a) always make a backup before fiddling around with your site
    b) professional – and free of charge – plugins like this may require more indepth knowledge about your server
    c) It is easy to point fingers, but Frederick seems genuinely interested in fixing possible bugs and even replies to mails faster than many paid services.

    Thanks
