Fatal error: Cannot unset string offsets in /wp-includes/widgets.php on line 622

UPDATE –
Well I found that there is more than one issue… I removed the wp_ prefix as described in a post I found, and now I am at the wordpress install screen, but it won’t accept any input.

UPDATE –
Ok, so what it seems like to me is that none of the data entered into any forms on my website is making it back to the server for processing. No matter what you enter into any text boxes is treated as blank data. Does that make any sensE?

Please anyone? I am getting the same error with a fresh install in a database that has never been used before ??

i’m getting very similar errors with a fresh install and fresh database.
everything installs ok but i get
path//wp-includes/widgets.php on line 621
when i click on any internal link on front page and then the front page will not display again. can’t log in as admin either
i’ve tried fresh installs…new databases.
i haven’t added any widgets/plugins and the theme is default.

I had the same problem and ended up adding to lines to my wp-config.php file:

ini_set(‘magic_quotes_gpc’,0);
ini_set(‘magic_quotes_runtime’,0);

Hope this helps!
