This function requires PHP 5.3+. I will search the replacement. Will you plan to switch to the higher PHP version than your current one (5.2.*) ? * [Greg Greensky](https://wordpress.org/support/users/greg-greensky/) * (@greg-greensky) * [10 years, 4 months ago](https://wordpress.org/support/topic/fatal-error-1986/#post-7012435) * Having that error too with PHP 5.2.12. Updating PHP on shared hosting requires admin action. * Temporarily uninstalling the plugin until something changes (either your code or the PHP on my shared sever). * Plugin Author [Vladimir Garagulya](https://wordpress.org/support/users/shinephp/) * (@shinephp) * [10 years, 4 months ago](https://wordpress.org/support/topic/fatal-error-1986/#post-7012442) * Fix was committed to the dev version [https://downloads.wordpress.org/plugin/user-role-editor.zip](https://downloads.wordpress.org/plugin/user-role-editor.zip) Call to `get_called_class()` was excluded. The oldest PHP version available to me is 5.4. Could you please test dev version against PHP 5.2 at your hosting? * [Greg Greensky](https://wordpress.org/support/users/greg-greensky/) * (@greg-greensky) * [10 years, 4 months ago](https://wordpress.org/support/topic/fatal-error-1986/#post-7012451) * Nope, now I get: * Plugin could not be activated because it triggered a fatal error.
