I wanted to create a sandbox site so I can work on a redesign and have the owners play with new content and such, so I created a full copy, created a duplicate database, put the files in a new folder, dumped the database in the new one, updated wp-config with the new db settings, edited the db entries for the URL, and fired up the site.
And this is what I get now:
Fatal error: Call to undefined function get_translations_for_domain() in /path/to/my/domain/wp-includes/l10n.php on line 81.
Funny thing is, the original site works fine, and I checked all the files, they're all there. What am I doing wrong here? Can anyone give me some help? I'm not a n00b, but this baffles me.
