    I updated my W3 Total Cache plugin and it gave me an error message saying that it failed. To try and fix it, I deleted the plugin and reinstalled it following these directions.

    https://www.ads-software.com/plugins/w3-total-cache/#installation

    I set the permissions to 777 and reinstalled the plugin, but it is still saying it failed. Even though it has failed, the plugin appears in WordPress and I can access the settings. When I run a compatibility test I get the following results…

    Plugin Version: 0.9.7
    PHP Version: 5.5.22;
    Web Server: Apache
    FTP functions: Installed (required for Self-hosted (FTP) CDN support)
    Multibyte String support: Installed (required for Rackspace Cloud Files support)

    Mime type detection: Installed (Fileinfo) (required for CDN support)
    Hash function: Installed (hash) (required for NetDNA / MaxCDN CDN purge support)

    mod_rewrite: Not detected (required for disk enhanced Page Cache and Browser Cache)
    mod_setenvif: Not detected (required for disk enhanced Page Cache and Browser Cache)

    How do I fix the plugin to fully install? Is the failed message a mistake since I can still access the plugin and it seems to be working? Should the last 9 line items in the compatibility test be detected?

    Any help is appreciated.

    The plugin uses the function apache_get_modules to get the available/enabled modules. Not detected means the function does not exist, or it returned an empty array, otherwise it would display Not installed. So you might have to look into why apache_get_modules doesn’t work.

    If you can access the settings, I think the installation went well. Do you get the message too when installing other plugins?

    Thank you for the quick reply.

    Do you have any directions or know a website that explains how to test why apache_get_modules is not working? I am not familiar with it.

    All of my other plugins updated fine and are working properly.

    I don’t know of any website, but a google search might help.

    I’ll try to find out the cause of installation failed messages so we can figure out what happens.

    Hi Gidomanders –

    I wanted to see if there was any update on the failed install message.

    Thanks

    Did you set permissions on the wp-content/upgrade directory to 777? And have you tried removing the directory and install the plugin then? The upgrade directory might be the cause of the installation failed message.

    Also this post might help you figure out the apache_get_modules() issue:

    Thank you for using W3 Total Cache!

    it took two tries but it re-installed with no errors, but with the following notification: Disk Enhanced mode can’t work with “Default” permalinks structure

    I set wp-content & wp-content/upgrade & wp-content/plugins to 777.

    The first time it errored it would not activate. Tried to delete and that did not work. At the top of the dashboard it said to delete advanced-cache.php, db.php, and object-cache.php. Then the plugin deleted.

    Second try, I installed it and it activated with no errors.

    You are using Page Cache Disk: Enhanced, which only works if you change your permalink structure in Settings => Permalinks to something like /%postname%/. That’s what the notification is about.

    Thank you. I changed it to /%postname%/ and the error message went away.
