Error in formatting.php

I just switched from Blogger to WP this past weekend and I’m getting this error message at the bottom of some posts (both new posts and older ones I edit). I need to delete the post to be able to display the blog again.

I tried changing themes but the error is still there.

Catchable fatal error: Object of class stdClass could not be converted to string in /home/buthman/public_html/blog/wp-includes/formatting.php on line 1229

These are lines 1228-1230:

function stripslashes_deep($value) {
$value = is_array($value) ? array_map(‘stripslashes_deep’, $value) : stripslashes($value);
return $value;

Ruuning 2.9.2

Thanks in advance!
