I think it might because of when this plugin is updating online on WordPress, it updated `full-site-cache-kc.php` before `functions.php`, so it have this problem. Try to install this plugin via FTP, or deactivate this plugin before update. * The new version had fix this bug, if functions.php not exist, returns a error and not effect WordPress. * If the error still exist, please tell me. * Thread Starter [gonebeta](https://wordpress.org/support/users/gonebeta/) * (@gonebeta) * [10 years, 2 months ago](https://wordpress.org/support/topic/error-when-activating-plugin-24/#post-7187933) * Thanks!

I tried that’ it didnt help. I’ll wait for the update. Maybe I’ll try something else out for now though because I still want to be able to use cache plugin on the site. * thanks for all your effort! * Plugin Contributor [ze3kr](https://wordpress.org/support/users/ze3kr/) * (@ze3kr) * [10 years, 2 months ago](https://wordpress.org/support/topic/error-when-activating-plugin-24/#post-7187979) * Yes, I found why this error happened. I did’t push some code directly to the SVN. Now this plugin is able to work. * Thread Starter [gonebeta](https://wordpress.org/support/users/gonebeta/) * (@gonebeta) * [10 years, 2 months ago](https://wordpress.org/support/topic/error-when-activating-plugin-24/#post-7187998) * Better now. I can generate the detail but I can ‘t seem to go past the first stage ( I am using cloudflare.co for my DNS could that be the problem? * Basically, I can’t login to wp-admin.mysite.com after implimenting the dns change even an hour after that. * in the first data generated in section one I saw this info there: * $fsckeycdn_useHTTPS = false; – shouldn’t that be true if I am using letsencrypt? * Also, do I need to first create the zone info on keycdn with the exact same info generated in the section you labelled “Add following DNS records, replacing existing records, BIND format DNS:”? * Because once I enter that into cloudflare the domain could become unreachable. * Thread Starter [gonebeta](https://wordpress.org/support/users/gonebeta/) * (@gonebeta) * [10 years, 2 months ago](https://wordpress.org/support/topic/error-when-activating-plugin-24/#post-7188002) * Something else just occurred to me. referencing ip address as the origin server would almost always result in error for servers with multiple site on the same IP address. All my vps servers use serverpilot.io instead of cpanel. * I was able to solve that using this method [https://serverpilot.io/community/articles/how-to-preview-apps-before-they-are-live.html](https://serverpilot.io/community/articles/how-to-preview-apps-before-they-are-live.html) * So, the sites need to use a custom url, but not ip address to work. * Plugin Contributor [ze3kr](https://wordpress.org/support/users/ze3kr/) * (@ze3kr) * [10 years, 2 months ago](https://wordpress.org/support/topic/error-when-activating-plugin-24/#post-7188013) * First, you need to use custom URL. And you don’t need to add zone by you self, this plugin will add the zone automatically. And $fsckeycdn_useHTTPS = false; doesn’t effect your KeyCDN HTTPS, it set to false because it detect your server doesn’t support HTTPS. If your server support, please go to CloudFlare and turn ssl to full ssl. * The domain will be unreachable until you go to the next step. * Plugin Contributor [ze3kr](https://wordpress.org/support/users/ze3kr/) * (@ze3kr) * [10 years, 2 months ago](https://wordpress.org/support/topic/error-when-activating-plugin-24/#post-7188014) * And you need to check origin server IP, the results isn’t always right, especially you use shared hosting. This plugin will send a HTTP request to your server itself to check the server own IP, it’s works well at most of time, but not always work. * Thread Starter [gonebeta](https://wordpress.org/support/users/gonebeta/) * (@gonebeta) * [10 years, 2 months ago](https://wordpress.org/support/topic/error-when-activating-plugin-24/#post-7188017) * Thanks! Almost there! 🙂 I went through the first two steps and it automatically created a zone and all that’s needed on keycdn. * The login and and https all works great! thanks! The site seems to work fine but I couldn’t go to the next step because of this error: * Fatal error: Uncaught Error: Cannot use object of type WP_Error as array in / srv/users/serverpilot/apps/mysitename/public/wp-content/plugins/full-site-cache- kc/functions.php:512 Stack trace: #0 /srv/users/serverpilot/apps/mysitename/public/ wp-includes/plugin.php(525): fsckeycdn_control_options(”) #1 /srv/users/serverpilot/ apps/mysitename/public/wp-admin/admin.php(236): do_action(‘settings_page_f…’)# 2 /srv/users/serverpilot/apps/mysitename/public/wp-admin/options-general.php( 10): require_once(‘/srv/users/serv…’) #3 {main} thrown in /srv/users/serverpilot/ apps/mysitename/public/wp-content/plugins/full-site-cache-kc/functions.php on line 512 * What should I be doing next? * Thread Starter [gonebeta](https://wordpress.org/support/users/gonebeta/) * (@gonebeta) * [10 years, 2 months ago](https://wordpress.org/support/topic/error-when-activating-plugin-24/#post-7188018) * I refrashed that page after about 30 minutes to see what could be going on and that error was gone but replaced with this one: * Warning: Invalid argument supplied for foreach() in /srv/users/serverpilot/apps/ mywebsiteurl/public/wp-content/plugins/full-site-cache-kc/functions.php on line 39 * Plugin Contributor [ze3kr](https://wordpress.org/support/users/ze3kr/) * (@ze3kr) * [10 years, 2 months ago](https://wordpress.org/support/topic/error-when-activating-plugin-24/#post-7188072) * Please check does zonealias is created or not. This plugin will also automatically create zonealias for you, but it seems that the request to create zonealias is timeout and this plugin doesn’t set a fault-tolerant for that, it will be fix in the next version. * And if the zone is created, add zonealias by yourself. And go to the settings page of this plugin, if it show the purge button, it means you have done all setup.
