functions.php line 920 causing problems…

I’m having two problems with a new install of WP 1.5.

Here is the error log generated when I open up the \wp-admin folder, which invokes index.php I guess:

Warning: Missing argument 2 for do_action() in /home/brownfam/public_html/idiot/wp-includes/functions.php on line 920

I haven’t been able to find anything about this in the support literature, but I’ll keep pecking away.

This second one is driving me nuts.

I’ve opened up functions.php with UltraEdit and check that the first and last lines are correct… no extra spaces or extraneous text. I don’t know the PHP code, so I really don’t know what’s happening @ line 920, but it is fouling me up pretty good.

I’ve downloaded functions.php, deleted it from the website folder, cleaned it up with UltraEdit, uploaded it to the site. Then I flushed my browser cache, cookies, and history and closed the browser.

Nothing seems to be helping here. I’ve made sure that this website is in my “trusted” list and that I can accept cookies from it.

Any ideas?
