[Plugin: W3 Total Cache] How to Uninstall with no Admin Panel (57 posts)

    do you know if the plugin would touch the Apache configuration?

    No it doesn't change that setting. It can't in fact.

    Are there any detailed documentation available (for setting up W3TC) ?

    I don't know what to say. I have 3 choices: 1. Remove all of the options and force people to optimize their sites as I desire. 2. Leave the options, keep reasonable defaults and let users read the captions and make their own discoveries. 3. Do #2 and write a 200 KB FAQ instead of my 100 KB one, trying to answer every conceivable question before it's asked. Basically write a book.

    I've chosen some of #3. I try to update the FAQ as I can.

    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.

    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: http://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

    To update on the white admin screen is I had. I got a chance to test out which other plugin might have conflicted.

    To activate W3, I of course had to deactivate all others first, then individually turn them on. In that order - I didn't get that white screen or any errors. I tried it this way twice (once on the original site and also once on the clone we have of that same site.) Both resulted in no problems and the plugin is running good.

    I would guess best that one of the other plugins conflicted during activation/installation only. So, Frederick, I don't really need an answer to that htaccess question above. If my result is helpful knowledge though, maybe that would be a "suggested try" - deactivate all plugins first, install, then reactivate them.

    Thanks for the great plugin!

    Sadly ive had the same problem on 2 sites. it is a shame as it does speed the site up, but i soon get the same problem going to wp-admin.

    I get the 'cant connect thing' and when you click more information its the internal server error

    checked ht access files, all ok. So not sure whats happening, i tried it with wordpress 3.0 and 3.1 and with different updates of the plugin, still the same problem.

    Sadly it seems that some other users have the same problem.
    hopefully one day we will be able to use this brilliant plugin.

    I cant risk the site not working by enabling it, so im going to delete it from my server

    Before you give up on it, make sure that you turn off ALL of your plugins before you activate w3tc. Then reactivate those others one at a time. I read that worked for someone else in another thread. Good luck.

    I also had the white screen problem on admin login with WordPress 3.
    The advice about which files to remove in wp-content worked fine.
    Many thanks Frederick

    Hi Frederick,
    I am having compatibility issues with Magic Fields and W3 Total Cache - any help you can provide is greatly appreciated. Basically, if I install w3 Total Cache on a site that I have Magic Fields active on, the WordPress admin will not show up. If I deactivate, install w3 Total Cache and reactivate, same result, and if I delete Magic Fields, install w3 Total Cache, reinstall Magic Fields and active, I get the same result.
    Thank you

    @itsmatthew I'm not familiar with that plugin. Have you contacted that plugin's author? A new forum topic is probably appropriate.

    Hello, im Facing a Problem.

    I followed the steps of removing the plugin but when i want to add a new page or add anything the page goes blank and when i reactivate the plugin everything goes back to normal.

    I Love Your Plugin But I Cant Add Custom Field Normally

    For Example When i type in Hello in the Name Field and Hello in the Value Field and click add it wont show the changes until i refresh the page!
    (when I Refresh the Page It Would Have Added A Duplicate of the name and values)

    i Opened .htaccess and deleted everything related to your plugin too

    If You Can Fix This I Would Be Grateful

    @xcool, not sure how that is occurring. Can you submit a bug submission from the support tab of the plugin please?
