Catchable fatal error: Object of class WP_Error could not be converted to string in /home/mynconne/public_html/wp-includes/wp-db.php on line 450

i have instaled a wordpress mu script and when i try to delete a page will show that error

you really need to share the script that you are using... not just the error..

specifically try to find the portion of the script that is causing the problem...

anyone have a solution for this error?

I do

Make sure you pass a string to whatever function you are calling.

I think it is because you are calling print or echo on an object without a __toString method defined. I believe you can no longer do this in PHP5.2+ (don't quote me on that). Wordpress uses a class WP_Error to pass error messages between methods. Calling print on an instance of this class will fail if it does not have a __toString method. You mentioned that you installed a "mu script", do you mean a plugin? If so it may not be compatible with your version of wordpress, or PHP.
