[resolved] W3TC has stopped Plugins from showing. It is blank (3 posts)

    Hi there,

    I have a problem with the W3 Total Cache plugin. It was working fine, but now I cannot view the Plugins screen, so I cannot deactivate it.

    I know about http://wordpress.org/support/topic/w3tc-0928-killed-my-backend?replies=17#post-4198702

    But commenting out line 127 did not work:

    w3_wp_request_filesystem_credentials();

    Any ideas?

    I think I solved the problem. I went into the Database and disabled the plugin in the Options table, active_plugins field. That brought the Plugins screen back.

    I deleted a:2:{i:1;s:37:"social-media-widget/social-widget.php";}

    I found more problems when I tried to delete the directory. It then caused more issues. So a complete uninstall sequence:

    To disable dodgy W3 Total Cache:
    1. I went into the Database and disabled the plugin in the Options table, active_plugins field. That brought the Plugins screen back.
    2. Delete dir /plugins/w3-total-cache to w3-total-cache.
    3. In .htaaccess, remove:
    # BEGIN W3TC Page Cache core
    <IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /
    RewriteCond %{HTTP:Accept-Encoding} gzip
    RewriteRule .* - [E=W3TC_ENC:_gzip]
    RewriteCond %{REQUEST_METHOD} !=POST
    RewriteCond %{QUERY_STRING} =""
    RewriteCond %{REQUEST_URI} \/$
    RewriteCond %{HTTP_COOKIE} !(comment_author|wp\-postpass|w3tc_logged_out|wordpress_logged_in|wptouch_switch_toggle) [NC]
    RewriteCond "%{DOCUMENT_ROOT}/wp-content/cache/page_enhanced/%{HTTP_HOST}/%{REQUEST_URI}/_index.html%{ENV:W3TC_ENC}" -f
    RewriteRule .* "/wp-content/cache/page_enhanced/%{HTTP_HOST}/%{REQUEST_URI}/_index.html%{ENV:W3TC_ENC}" [L]
    </IfModule>
    # END W3TC Page Cache core
    Then upload this file to root.
    4. Rename files /wp-content/advancedcache.php to advancedcache.phpBADD and objectcache.phpBADD
