 * Hi all…I just upgraded to the lastest version and am now getting an error message.“
   Warning: Missing argument 2 for wpdb::prepare(), called in /home/blackcof/public_html/
   wp-content/themes/switchblade-v1.3/framework/sidebars.php on line 79 and defined
   in /home/blackcof/public_html/wp-includes/wp-db.php on line 992”
 * Also, my style sheets seem to have gone haywire!
 * This is my site: [http://blackcoffeecommunications.com.au/](http://blackcoffeecommunications.com.au/)
 * Can it be fixed, or can I go back to the older version???
 * Help!

 * You have a bad plugin or theme. Have you tried:
 * – deactivating **all** plugins to see if this resolves the problem. If this works,
   re-activate the plugins one by one until you find the problematic plugin(s).
 * – switching to the default theme to rule out any theme-specific problems.
 * – [resetting the plugins folder](http://codex.wordpress.org/FAQ_Troubleshooting#How_to_deactivate_all_plugins_when_not_able_to_access_the_administrative_menus.3F)
   by FTP or PhpMyAdmin. Sometimes, an apparently inactive plugin can still cause
   problems.

 * I’ll try 🙂
 * If it is a problematic plug in or theme, why was it fine before the upgrade?

 * Because the upgrade fixed an issue in WordPress core.

 * Mmm…deactivating the plugins did nothing, but when I went to a default theme 
   it was fine…time to contact the theme developer!
