Just activating plugin (not even enabling cache) breaks site

    WP 4.5.3 + latest version of W3 Cache. Apache 2.4 + PHP 5.4 is used. Once I activate the plugin, admin area stops working properly. These issues exist:

    1. Auto updating plugins fails. Once the message “turning on maintenance mode” is displayed, page stops loading and nothing happens. I need to manually delete .maintenance file and deactivate W3 cache to update plugins.

    2. Visual Composer doesn’t work. If I try to edit any page, an empty text area (just like when creating a new page) is displayed, nothing happens.

    3. Yoast SEO doesn’t work too. When editing page, no SEO snippets are displayed.

    The most interesting part is that it happens even when ALL MODULES ARE DISABLED and plugin displays message “plugin is disabled”. In order to fix the issue, I need to manually deactivate the plugin itself via Plugins window.

    Also, when running compatibility check, W3 cache doesn’t detected many mods (like mod_rewrite, expires, etc.) even if they are installed and work well on server.

    Frontend of website works perfectly for logged in and not logged in users all the time, even when all caching modules are enabled in plugin. Only admin area stops working properly when plugin is activated.

    Hello lipskas

    Do you see any error in browser console? Please go to such page in Chrome where you were having issues, right click > select inspect element > select console > refresh the page and check if any error is printed in there. If so, please post the error messages in here.

    Also, would you please post a list of plugins that are activated w/ W3TC?

    Have a good day!

    Cheers

    Thanks for the answer. I see these 3 errors in console:

    11:02:44.931 TypeError: $(…).wpColorPicker is not a function
    <anonymous> themex.interface.js:208
    n.Callbacks/i() load-scripts.php:2
    n.Callbacks/j.fireWith() load-scripts.php:2
    .ready() load-scripts.php:2
    K() load-scripts.php:2
    1 themex.interface.js:208:2

    11:02:45.052 downloadable font: rejected by sanitizer (font-family: “dashicons” style:normal weight:normal stretch:normal src index:0) source: http://MY_DOMAIN/wp-includes/fonts/dashicons.eot1 load-styles.php:1:11

    11:02:45.059 window.controllers is deprecated. Do not use it for UA detection.1 nsHeaderInfo.js:412:8

    These plugins are enabled:

    Better Font Awesome
    Contact Form 7
    iThemes Security
    Share Buttons by AddThis
    Simple Mathjax
    TablePress
    W3 Total Cache
    WooCommerce
    WPBakery Visual Composer
    Yoast SEO Premium

    P.S. I just checked some other types of records (like courses, lessons, since it’s a learning website) in admin area, and YoastSEO works fine for those pages even when W3 is enabled. These pages also have “downloadable font: rejected by sanitizer” and “window.controllers is deprecated” errors, but work fine. However, they don’t have “TypeError: $(…).wpColorPicker is not a function” error.
