WordPress Bug- Admin are problems in Opera

The dashboard is fine for me using Opera 11.50. 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 Twenty Eleven 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.

I have the same problem. I was using Opera 11.11. I have tried on 3 different sites, twice in WordPress 3.2 and once in WordPress 3.2.1. I upgraded to Opera 11.50 and the problem remains. Visual editor stops working. This is using Opera on 64-bit Linux.

Here is a Javascript Exception from Opera’s log after a copy-paste operation; after this exception, all visual editor operations stopped working.

I’m having serious Opera problems as well since upgrading. These problems happen on multiple sites on multiple web hosts on multiple themes and plugin configurations. What can we do to help fix this problem?

Recently, I have discovered (and fixed) a bug in TinyMCE, which Livefyre uses and also has the bug.
For the “getRangeAt, INDEX_SIZE_ERR” JavaScript error, have a look at my blog post.

TinyMCE JavaScript error in Opera (getRangeAt, INDEX_SIZE_ERR):
https://my.opera.com/XP1/blog/2011/07/21/tinymce-javascript-error-in-opera-getrangeat-index-size-err

See my pull request here:
https://github.com/tinymce/tinymce/pull/77/

Let me know if testing reveals that it works or doesn’t work.

This TinyMCE bug was previously reported from at least 2011-04-14, yet has not been fixed (until now, hopefully). See TinyMCE bug reports #4306 and #4372 (duplicate).

This one JavaScript error is what seems to be causing all types of problems, including the CTRL + V paste bug and the underscore bug. I fixed the bug and submitted a pull request (see above).
