Support » Plugin: W3 Total Cache » Won’t activate – false detection of multisite

  • This plugin gives a fatal error when attempting to activate saying; “Please network activate W3 Total Cache when using WordPress Multisite.”

    The problem is I no longer have WordPress multisite set up, and there is no information on how the plugin detects multisite or how to correct the false detection

    The restrictions on installing/activating a plugin on a multisite WordPress installation are not built in the plugin. It is core WordPress functionality.
    The wrongful detection of being a multisite could be multiple things. Please check if any of these are true:

    * There’s a define(‘MULTISITE’, true); somewhere, most likely in your wp-config.php
    * There’s a define(‘WP_ALLOW_MULTISITE’, true); somewhere, most likely in your wp-config.php
    * There is a file named wpmu-settings.php in your root directory

    Any of the above could be the cause of your problem. Fix them and you’ll probably be able to install and activate the plugin successfully.

    Hi there,

    I also face the same issue. I went through the checklist and did not find anything there.

    any other suggestions?

    @antipath maybe you should submit a support request through Performance => Support so we can check your system for any misconfiguration.

    Same problem here, and none of the above solutions worked.
    I am not running a multisite network!
