Sidebar gone after database prefix change

Hi all,
I just dropped my db and managed to recover it but my sidebars have disappeared.
I exported my sql file, opened it and ran a find-and-replace to clear up the defaults with custom ones. I’m sure I replaced all, and obviously wp-config.php reflects this change.
But I’m wondering why this is happening.

Please help me, if anything remotely similar has happened to you, or if you happen to grasp the situation let me know.
Thanks in advance.
