 * Try to update your theme and make sure your theme is 2.0+ compatible.

 * I’m using [http://themeforest.net/item/nevada-responsive-multipurpose-theme/3087951?sso?WT.ac=portfolio_item&WT.seg_1=portfolio_item&WT.z_author=UnitedThemes](http://themeforest.net/item/nevada-responsive-multipurpose-theme/3087951?sso?WT.ac=portfolio_item&WT.seg_1=portfolio_item&WT.z_author=UnitedThemes)
   but I designed the theme with WP 2.0+ and never had a problem until about an 
   hour ago until today’s release.
 * I did find a “fix but it seems to have made it go from bad to worse. Nevada forum
   says:
 * To BillGray: Please do not agitate people here around. If you missed the steps
   above you have made at least a failure too so do not blame us here.
 * However here is the temporary fix until we have an official update ready at themeforest:
 * Exchange the theme functions.php with the one attached and delete the following
   file on the web server:
 * wp-content/themes/nevada/woocommerce/widgets/lambda_woo_login.php
 * as stated here inside the change logs [http://wordpress.org/extend/plugins/woocommerce/changelog/](http://wordpress.org/extend/plugins/woocommerce/changelog/)
 * Please use this login widget instead : [http://wordpress.org/extend/plugins/sidebar-login/](http://wordpress.org/extend/plugins/sidebar-login/)
 * Did all this and now NO SITE and new error [http://www.essentialbodywisdom.com/](http://www.essentialbodywisdom.com/)
 * Fatal error: Call to undefined function get_option() in /home/essentia/public_html/
   wp-includes/functions.php on line 18
