Disable warning message in Safari 5.1.2 I got a weird warning message in Safari 5.1.2 :

Safari support is very limited and should be considered experimental.
So there is no need to even submit bugreports on this early version.
You can disable this message by setting: safari_warning option to false


Where i can find safari_warning option to change it to false ?
This error message is not coming from Safari.  It's coming from the content management system of the website: the SLAED CMS, in particular from the editor this CMS uses, TinyMCE.  There isn't anything you can do.  The website author needs to change this setting on their site or upgrade the CMS/TinyMCE version.  The site you refer to is running a version of TinyMCE from 2005 when Safari support was new.
