 * I tried to download s2member plugin but I got the following message:
    Fatal error:
   Call to undefined function bp_is_register_page() in /home/princess/public_html/
   wp-content/plugins/s2member/includes/classes/systematics.inc.php on line 109
 * How do I uninstall this plugin? I can’t seem to get back into the cpanel without
   this error message being displayed. Help!

   so that every s2MEmber folk can help.

 * Try switching to the Twenty Eleven theme by renaming your current theme’s folder
   in wp-content/themes and adding “-old” to the end of the folder name using [FTP](http://codex.wordpress.org/FTP_Clients)
   or whatever file management application your host provides.
