I am getting an Akismet error message after upgrading from 2.05 to 2.1.3.
Instead of blowing away my entire 2.05 installation, I renamed the directory containing the 2.05 install and created a new dir and put the 2.1.3 WP files in it.
When I first ran WP from the dir where I have 2.1.3 installed, WP said it 'upgraded' the SQL db.
Now I get this error message in the akismet error log:
[22-Apr-2007 18:09:42] PHP Fatal error: Call to undefined function: add_action() in /home/machineg/public_html/shao/wp-content/plugins/akismet/akismet.php on line 26
I tried removing akismet from the plugins directory and reinstalling it but this doesn't help.
