 * not sure what I’ve done here – I’m trying out the latest development snapshot…
 * When I try to activate a Plugin I get:
 *  Warning: Invalid argument supplied for foreach() in D:\webworld\bantryyouth\
   bantryyouth.net\www\wordpress\wp-admin\upgrade-functions.php on line 842
 * Anyone help please??
 * Thanks

 * Getting closer…. I had KIWI plugin installed – once deactivated, the foreach 
   error goes away…
