Please help: I received the following error:
Fatal error: Call to undefined function language_attributes() in /home/speroinc/public_html/wp-content/themes/SPERO2/header.php on line 2
I followed instructions to manually upgrade from 2.5.1 to 2.7.
After uploading the files I went the blog site [ http://www.speroinc.org/wp-admin ] to initiate the upgrade.
I followed instructions to upgrade the database - which I did successfully.
However, now I can not log in with my password and I get the fatal error when I try to view the home page.
