    Since the errors have to do with stuff in the wp-includes folder, I would delete that folder from your webhost and upload it again. Just for safe measure, I would do the same with the wp-admin folder.

    Make sure and delete the folders from your blog directory first.

    I will try to do it what you said,
    and thank you for your help.

    Same here, total disaster.

    Since 2.3 wordpress upgrades have never been smooth 🙁


    I’m on 2.3 – is it better to stick to that rather than 2.5, because a lot of peeps out there seem very upset, angry and frustrated that 2.5 has caused so many woes?

    These are support forums. 99% of the people posting here have problems, by definition.

    On the contrary, this is one of the most problem free releases yet. Normally there’s *way* more people complaining. 🙂

    i have upgrade my wordpress from 2.3.3 to 2.5, and it’s look nice 😀
    and i have no problem with it..
    i’m only copy and replace all of wp 2.3.3 file with 2.5

    I upgraded from 2.0.something and the only problem I had were out of date plugins, but I expected that to happen. In fact, one of the plugins was causing me to have the “headers already sent” error, so if reuploading the wp-includes directory doesn’t fix the problem, you might look at your plugins.

    I deleted all the plugins which I had that did not come with WordPress and then uploaded WordPress 2.5 again.

    Nothing has changed. There is the following message on my blog:

    Warning: array_merge() [function.array-merge]: Argument #2 is not an array in /home/verotaro/public_html/motorparasi/wp-includes/widgets.php on line 60

    I don’t know what to do.

    First of all thanks to everyone. I have 3 other blogs and the upgrade to WordPress 2.5 went smoothly.

    I had this problem with the last upgrades. I went into my old emails and found a support answer from my webhosting provider. They found the answer so we tried this solution to the current upgrade problem and it worked like magic.

    The solution is located here:


    I put the one line of code in the widgets.php file on the line number that was the problem (for me it was line 60 – the old code was
    $sidebar = array_merge($defaults, $args);

    The proper code should be:
    $sidebar = array_merge($defaults, (array)$args);

    Hope this helps someone else.

    emirhan: No, that’s not your problem. The real problem is in your theme, it’s making a call to the register_sidebar function with incorrect parameters. I suspect that it’s something like register_sidebar(2); in your theme’s functions.php file, when it should really be doing register_sidebars(2);. Note the extra “s”.

    I upgraded from WP 2.3.1 (I think!) to 2.5 and I had the following problem. The blog appeared as expected, but when I tried to login as admin – a blank page appeared!

    The problem is the same as the user describes in this forum:

    There is an answer from another user, but I do not understand what he actually means or what the problem is – Does he mean that I should go through the installation process again as I did here: http://codex.wordpress.org/Upgrading_WordPress

    When I tried to re-install my backup, it just worked the other way around – the blog page was blank, but I could access as admin!

    I have tried to find an answer in the support fora, but nothing that really gives an answer…

    Hope you can help.


    I’m so happy, the blogs I own don’t have errors.
    5 of them
    but the one of my friend does causes errors >.<

    Hi Guys,

    This is regarding my previous post on the blank page and missing access via wp-login – I am now able to access the admin via my email with the comment link and WP 2.5 works fine! But I still can’t access via the wp-login. What could be the problem? Don’t know what to do…


    I get a “pluggable.php on line 689” error when I try to access my wp-admin page. I’ve re-uploaded the 2.5 upgrade files and checked that I followed the upgrade instructions.

    I downloaded the upgrade and copied the new files and I have the exact same problem. I’ve had problems on every upgrade since 2.0…ugh. i think i’m going to start ignoring the “please upgrade” messages.
