    after upgrading I get this error

    Fatal error: Call to undefined function has_filter() in /home/syntraab/default_www/wp-includes/classes.php on line 241

    anybody an idea how to solve it?

    That's a function that is defined inside wp-includes/plugin.php

    If there is a copy of that file on your site, delete it, and upload a fresh copy out of the zip.

    See if that helps.

    it's solved by uploading again and first deleting indeed

    I'm getting the same problem! Replacing all of the wp-includes files doesn't help.

    My dashboard looks just like bankans' :(

    I had the same problem and admin looked like the picture that bankans posted...but deleteing the plugin.php file and re-uploading fixed it right off. Thanks!

    OK, fixed now - I uploaded *everything* again. I think my FTP client was only uploading newer files, and some of the new 2.5 files actually had an older datestamp than those on my server.

    well I have fixed the problem somehow but got the same in my other site.
    I am WP freak. All my sites (>10) are in WP. All but 2 gave me problem during upgrading so far. both gave me same problem though. with plugin.php and with wp-includes/classes.php on line 241

    I will try re uploading everything! and let you all know about my experience.

    I am noticing that "speed" for page load time has improved a LOT!

    here is my another site which is having problem:
    http://ankanbasu.com

    while http://coalgeology.com behaving superb.
