Can't switch to HTML view when posting or editing a page/post

I have had it with WordPress. One after another bug. Same problem here.

Well, it seems to be a Safari problem. Works with Firefox.

Seems to be deeper than just a safari problem. I’m working a new site and i cant access it too with Chrome10, Safari5, FF4, Opera10 and ie9! Dont work for both posts and pages for this wp installation. On other sites with also wp 3.1, it’s fine. Pretty annoying.

Update: just saw that i had both options (html and visual) at the same time in the ‘visual’ tab. None of the html options working though.

Update2: don’t know if it’s linked but i also cant drag and drop the items in the menu editor. Starting to get really annoying!

Have you tried:

– switching to the Twenty Ten theme to rule out any theme-specific problems.

– resetting the plugins folder by FTP or PhpMyAdmin. Sometimes, an apparently inactive plugin can still cause problems.

– re-uploading the wp-admin and wp-includes folders from a fresh download of WordPress.

– increasing the memory available to PHP:

Found the bug, was from my functions.php file, i had:

wp_deregister_script( 'jquery' );
wp_register_script( 'jquery', ( 'https://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js' ), false, '1.x', true );

which was interfering with the admin.
So i updated to:

if(!is_admin()) {
	wp_deregister_script( 'jquery' );
	wp_register_script( 'jquery', ( 'https://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js' ), false, '1.x', true );
}

And it all works fine.
