Your version of PHP must be older than that. Hopefully you don’t have a version older than 5.2.0, because we do not support versions of PHP that are older than that. * I made a fix that will allow the plugin to run on 5.2.0. Assuming your version of PHP is at version 5.2.0 or above, you can try again in an hour or so. * Kevin * [kharlo](https://wordpress.org/support/users/kharlo/) * (@kharlo) * [15 years ago](https://wordpress.org/support/topic/fatal-error-at-activation/#post-2054806) * Hi Kevin, I have this error on activation: The Google PHP API Library needs the CURL PHP extension * I have PHP v5.2.0-8+etch15 what should I do? * thanks! kharlo * Plugin Author [kbm](https://wordpress.org/support/users/kbm/) * (@kbm) * [15 years ago](https://wordpress.org/support/topic/fatal-error-at-activation/#post-2054819) * Do you have root access to your system? You might need to recompile PHP to include CURL support, or install additional support packages (e.g. php5-curl on Ubuntu.) * [kharlo](https://wordpress.org/support/users/kharlo/) * (@kharlo) * [15 years ago](https://wordpress.org/support/topic/fatal-error-at-activation/#post-2054823) * no access… i’m in hosting… * Plugin Author [kbm](https://wordpress.org/support/users/kbm/) * (@kbm) * [15 years ago](https://wordpress.org/support/topic/fatal-error-at-activation/#post-2054833) * Hello Kharlo, * Sorry, the plugin won’t work unless your hoster upgrades your PHP installation to support libcurl. * Fortunately, the plugin is not the only way to verify your site with Google. There are several manual verification methods you can use to verify your blog at [https://www.google.com/webmasters/verification/](https://www.google.com/webmasters/verification/). * There are also several other verification plugins available for WP that don’t rely on web service calls, and therefore shouldn’t require CURL libraries. * I hope that helps! * [chicagorealtor](https://wordpress.org/support/users/chicagorealtor/) * (@chicagorealtor) * [14 years, 7 months ago](https://wordpress.org/support/topic/fatal-error-at-activation/#post-2054908) * Can someone help me with this error message?
