Hi..i have installed a plugin(Google Toolbar Button) in wordpress in my local machine..when i try to activate it...it shows Plugin could not be activated because it triggered a fatal error. plz help...
Tell us about the error message you've got. Re-download the plugin, then reinstall it to your WordPress.
Maybe your activated theme doesn't place the common used hooks (I mean <?php wp_head(); ?>, <?php wp_footer(); ?>, as well as other hooks) in the source code?
