W3TC 0.9.2.8 Killed My Backend

    I just updated to WordPress 3.5.1 and W3TC 0.9.2.8 at the same time. Site is still live, but my backend is dead – it gives me the white screen with the error message below. I tried adding a blank ‘master.php’ file to /wp-content/w3tc-config without any success.

    Fatal error: Uncaught exception 'FileOperationException' with message '<strong>/home/recaptur/public_html/wp-content/w3tc-config/master.php</strong> could not be created, please run following command:<br /><ul><li><strong style="color: #f00;">chmod 777 /home/recaptur/public_html/wp-content/cache/tmp</strong></li><li><strong style="color: #f00;">chmod 777 /home/recaptur/public_html/wp-content/w3tc-config</strong></li>' in /home/recaptur/public_html/wp-content/plugins/w3-total-cache/inc/functions/activation.php:127 Stack trace: #0 /home/recaptur/public_html/wp-content/plugins/w3-total-cache/lib/W3/ConfigWriter.php(159): w3_throw_on_write_error('/home/recaptur/...', Array) #1 /home/recaptur/public_html/wp-content/plugins/w3-total-cache/lib/W3/Config.php(71): W3_ConfigWriter->save() #2 /home/recaptur/public_html/wp-content/plugins/w3-total-cache/lib/W3/CloudFlare.php(174): W3_Config->save() #3 /home/recaptur/public_html/wp-content/plugins/w3-total-cache/lib/W3/Plugin/CloudFlare.php(52): W3_CloudFlare->update_ip_ranges() #4 /h in /home/recaptur/public_html/wp-content/plugins/w3-total-cache/inc/functions/activation.php on line 127

    Can someone please walk me through how to fix this?

  • Hi there,

    I have a similar problem. W3TC has stopped my Plugins directory from loading, so I cannot deactivate it.

    I tried commenting out line 127:

    w3_wp_request_filesystem_credentials();

    But that did not work? 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.

    In fact, i deleted i:2;s:33:"w3-total-cache/w3-total-cache.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. Rename dir /plugins/w3-total-cache to w3-total-cacheBADD.
    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
