Visual Editor is not working: toolbars gone

Try deactivating all plugins. If that resolves the issue, reactivate each one individually until you find the cause.

If that does not resolve the issue, try switching to the Default theme (WordPress 1.5 – 2.9.2) or the Twenty Ten theme (WordPress 3.0 and higher) to rule-out a theme-specific issue (theme functions can affect the admin panel).

well, problem remains..
reinstall WP? ??

Make sure the ‘Disable the visual editor when writing’ option on your Profile page is unchecked.

I tried it too… the option was unchecked, even so I tried check and uncheck again.. and the problem still remains.
Another suggestion?

well, what’s the most secure way to start again without losing data?… ??

Have you tried:

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

– increasing the memory available to PHP?

Hi dear friends.. I’ve tried something just a little different that proposed by esmi: I’ve installed a completely new download of WP, copied plugins and redirected to the old database. It’s worked.
Thanks a lot for the attention. ??
