My site was just moved to a new server (with the same URL). I updated the wp-config.php file with my new mySQL data, and got this error on my index page:
"Fatal error: Call to undefined function language_attributes() in /home/.maska/solilo_martha/migratorymushroom.soliloquise.com/wp-content/themes/default/header.php on line 2"
Also, if I try to log in to the admin panel using the "admin" username, it gives me an "invalid username" error.
Any ideas on how to fix this?
