Hi!
I cannot login to the back-end of the site, I’m getting this error:
[code]Fatal error: Call to undefined function get_home_path() in /home/racinne/public_html/wp-admin/includes/misc.php on line 16[/code]
Perhaps this is related to the search issue? The error is coming from a WordPress core file, you should definitely check, it might lead to other errors as well.
