WordPress MU

Hi
I'm getting this weird message when I try to activate wp-pagenavi plugin in MU?

Fatal error: Cannot redeclare wp_pagenavi() (previously declared in /home/artygirl/public_html/wp-content/themes/CSSGallery/functions.php:87) in /home/artygirl/public_html/wp-content/plugins/wp-pagenavi/wp-pagenavi.php on line 180

Anyone know how to fix it? I have wordpress 2.8.4a!

Thanks
Judi

Well its falling over because the other plugin (CSSGallery) has already declared a function called wp_pagenavi.

So you could try removing the wp_pagenavi plugin but leave the navigation code in the page and hope that the wp_pagenavi function in CSSGallery gives you the features you need.

Or you need to talk to the developers of the plugins.
