# Security error code 1000 from prototype

 * I have just upgraded from WP 2.2.3 to WP 2.3 and now I am getting the javascript
   error ‘Security error “code: ” 1000’ when I am loading the options pages for 
   a couple of my plugins (for example “Get Recent Comment” [http://blog.jodies.de/archiv/2004/11/13/recent-comments/](http://blog.jodies.de/archiv/2004/11/13/recent-comments/)).
   Some debugging leads me to prototype.js (line 1264) but that does not make any
   sense to me. I have tried everything I can think of, but without any success.
   I do not get the error when I run WordPress on my laptop, just when I have it
   on my web host which makes me suspect some security setting.
 * Is this something anybody has bumped into? Any ideas of what to try to fix this?
