Hello, i've just installed the Duotone theme on a self-hosted wordpress 2.9 instance. I tried the preview and it's giving me this error:
Warning: Missing argument 1 for is_vertical(), called in [...]/wp-content/themes/duotone/functions.php on line 18 and defined in [...]/wp-content/themes/duotone/inc/duotonelibrary.php on line 295
I'm currently using Monotone, which is still working fine.
Anyone had a similar problem? Hints?
