I am running Mu 2.7.1 and this is the error I'm getting in "Site admin > Options":
"Catchable fatal error: Object of class WP_Error could not be converted to string in /home/mysite/public_html/wp-includes/wpmu-functions.php on line 112"
I have tried askhoapham's phpMyAdmin solution with no luck.
When I browse my dashboard_blog table, there is no field in the Value column for meta_value. However, there is this message in the results window:
O:8:"WP_Error":2:{s:6:"errors";a:1:{s:10:"blog_taken";a:1:{i:0;s:20:"Blog already exists.";}}s:10:"error_data";a:0:{}}
I then went and made the changes to the two files detailed in the trac ticket and still getting the same error.

I appreciate any help.
Best,
